SGDH Sigma II

Why does the SGDH servopack flash "bb" continuously?

Posted Date: 09/06/2004

Answer:

1) The MP-940 24VDC is not connected, or the polarity of the power is reversed
2) The internal protection fuse (FU1) inside the MP-940 has been blown. (Attached please find the fuse specifications, 1.5A required, Cautionary Note: Field replacement of this field could void warranty)
3) The 24VDC power supply could be undersized, and inrush could causes a device to drop out. Keep the following specifications in mind when sizing the power supply:
Continuous power consumption:
MP-940 control power 0.4A
SGDH (400V) control power 1.0A (3.0A surge for 50msec)
(DC motor brakes should be powered by a separate supply to reduce noise)

4) If the MP-940 and SGDH are powered up together and successfuly synchronize but the SGDH subsequently loses control power and has it reapplied while the MP-940 24VDC remains constant, bb will blink.

5) If the MP-940 has been without power for over 24 hours without a backup battery attached, or the program is stored in flash.

Note: Firmware Version in SGDH: 14, MP-940: A05

Why does the Servopack display an AF1 alarm when main power is removed? None of the solutions in the User's manual remedy the problem.

Posted Date: 07/13/2004

Answer:

A.F1 (AF1) alarm is an open phase error.

Two potential external causes:

1) One or more of the contactor contacts are sticking and causing one or two phases to stay connected when they should open.
Solution: Replace/Clean contacts (if serviceable), or replace contactor.

2) Another possible cause: A power line filter has been improperly installed between the contactor and the ServoPack. The three phase power line filter discharges unequally and it appears to the ServoPack that there is an open phase.
Solution: Install power line filters properly, prior to the contactors in the electrical circuit. (Reference Section 3.1 in Sigma II User's Manual [YEA-SIA-S800-32.2] for wiring specifications)

Where can pin out details for the YS-12 cable be found?

Posted Date: 07/13/2004

Answer:

The attached drawing contains the full details on this serial (RS232) data transfer cable.

The following parts will be needed to make this cable:
1) Standard 9 pin female D shell connector (PC side).
2) 24 AWG x 2 pair, 300V shielded cable.
3) Qty. 1 of Yaskawa p/n YSC-1 (mates to 3CN on SGDH, or the 6CN or 7CN when used with Application Modules).
YSC-1 consists of 3M p/n's 10114-300VE (connector) + 10314-52A0-008 (shell). This part may also be found through other suppliers.

If it is necessary only to increase the length of the cable (and not to build the cable from scratch), a popular option is to buy the YS-12 cable and build a serial "extension" cable. The extension cable is not Yaskawa specific and can thus be used in other RS232 communication applications.

Note: Recommended maximum cable length for error free data transfer is 15 meters (50 feet). Longer cables are made at your own risk!

When using SigmaWin software, what are the units when graphing torque?

Posted Date: 07/13/2004

Answer:

When using a matched Servo Pack / Servo Motor combination (eg. SGDH-05xx, SGMGH-05xxxxx) the units are percentage of rated torque.

Sigma II allows (for emergency situations) operation of the Servo Pack / Servo Motor combinations of up two times larger or one-half smaller. This affects the units of the torque monitor by displaying the percentage of rated torque for the lowest rated component. For example:

If an SGDH-05xx and an SGMGH-09xxxxx were combined, the display units would be percentage of rated torque (current) for the SGDH-05xx.

If an SGDH-10xx and an SGMGH-05xxxxx were combined, the display units would be percentage of rated torque (current) for the SGMGH-05xxxxx.

When using an absolute encoder, is it possible to set the absolute zero position through the Fieldbus Network?

Posted Date: 01/09/2002

Answer:

An absolute encoder reset must be done to clear the A.81 alarm. For safety reasons, this can only be performed through the SGDH front panel with a Function 8 or through the monitor software. This operation is typically only performed at machine startup when the mechanical system is coupled to the motion control system.

Once the absolute zero is set, a new zero point can be established over the Fieldbus Network for the convenience of the user. Define the new zero point by using the Define Zero Point Command in the Set/Read section of Command/Response format - Section 5.3 of the NS300 User Manual.

When setting parameter Pn300 (Speed Reference Input Gain) what rated speed should be used for Linear Motor applications?

Posted Date: 07/13/2004

Answer:

The configuration of Parameter Pn300 is the same for Linear Motor applications as it is for Rotary Motor applications. The motor speed is controlled in proportion to the input voltage between V-REF (CN1-5) and SG (CN1-6). This is depicted in the attached .PDF file that includes graphs and setting examples.

For further information regarding adjustment of parameter Pn300, refer to the Sigma II Series Servo System User's Manual [YEA-SIA-S800-32.2] section 5.2.1.

What voltage levels will cause an overvoltage or undervoltage alarm?

Posted Date: 02/06/2009

Answer:

All Yaskawa Sigma and LEGEND series amplifiers input power specifications are +10% to -15%. 10% above the highest voltage input specified will cause an overvoltage alarm, while 15% below the lowest voltage specified will cause an undervoltage alarm.

For a 100-115 amplifier +10% / -15% equates to 85 VAC and 126 VAC respectively.
For a 200-230 amplifier +10% / -15% equates to 170 VAC and 253 VAC respectively.
For a 400-480 amplifier +10% / -15% equates to 340 VAC and 528 VAC respectively.

What voltage levels will cause an overvoltage or undervoltage alarm?

Posted Date: 03/02/2015

Answer:

All Yaskawa Sigma and LEGEND series amplifiers recommended input power specifications are nominal +10% to -15%.

For a 100VAC Class (100-115VAC) amplifier +10% / -15% equates to 75 - 126 VAC respectively.
For a 200VAC Class (200-230VAC) amplifier +10% / -15% equates to 170 - 253 VAC respectively.
For a 400VAC Class (380-480VAC) amplifier +10% / -15% equates to 323 -528 VAC respectively.

The A.400 (Overrvoltage) Alarm will occur at the following voltage thresholds:

For a 100-VAC Class amplifier 145 VAC or more
For a 200-VAC Class amplifier 290 VAC or more
For a 400-VAC Class amplifier 580 VAC or more
For a 200-VDC Class amplifier 410 VDC or more
For a 400-VDC Class amplifier 820 VDC or more

The A.410 (Ondervoltage) Alarm will occur at the following voltage thresholds:

For a 100-VAC Class amplifier 49 VAC or less
For a 200-VAC Class amplifier 120 VAC or less
For a 400-VAC Class amplifier 240 VAC or less
For a 200-VDC Class amplifier 170 VDC or less
For a 400-VDC Class amplifier 340 VDC or less
