	When running into hardware limits, motion is disabled in both directions. How can the axis be jogged off the limit switch? Posted Date: 07/13/2004 Answer: When running into a hardware limit switch with the MP940 controller, the drive decelerates the motor to a stop. The method of stopping depends on Pn001 setting. This also causes an A.9F alarm in MP940, which prevents the motor from moving. To enable and move the motor off the limit switch, the user must reset the alarm by toggling bit 6 of OWC000 in MW (The servo and the motion commands must be off before resetting.) If using MW+, the RESET FAULT icon must be executed. After the reset, the servo can be enabled and moved in the reverse direction of the limit.

	When replacing the motor for the application and the heat sink cooling fans. How do I reset Cumulative Motor Operation Time U1-13 and Heat Sink Cooling Fan Operation Time U1-40? Posted Date: 09/16/2013 Answer: When a motor replacement is needed, Cumulative Motor Operation Time (U1-13) can be reset with setting parameter o2-07=000000. When replacing the heat sink cooling fans on the drives, Heat Sink Cooling Fan Operation Time (U1-40) can be reset with setting parameter o2-10=00000.

	When reading 42h it does not match U1-03? Using Ethernet or Modbus protocols. Posted Date: 08/31/2012 Answer: When using 42h, please use the following formula: "Value of Read" divided by "8192" times "Drives Rated Output Current". You can also read 26h which does not require this formula.

	When moving away from a overtravel condition, the Sigma V servo system seems to prevent torque or rapidly enable/disable as the axis is moving out of the overtravel region. Can this situation be prevented? Posted Date: 10/06/2011 Answer: When the servo is controlled in position or speed mode, the ServoPack will not command torque the direction of an active overtravel. To completely prevent this condition when moving out of a overtravel region, use the MC_TorqueControl function block with a velocity limit and direction to move out of the overtravel region and prevent the torque "cutout" behavior from occurring. Otherwise, to reduce the torque cutout effects, turn off the controller feed forward setting, parameter 1310, which makes the condition more noticeable.

	When is it necessary to connect an external regen resistor to the SGDG LEGEND amplifier? Posted Date: 01/21/2002 Answer: Install an external regen resistor if the regenerative power from the load exceeds the processing capability of the LEGEND amplifier (usually associated with alarm #3: regen circuit error). Connect the resistor to terminals B1 and B2 on the Legend amplfier. On 1kW and 1.5 kW amplifiers, remove the jumper wire between B2 and B3 . Turn OFF #5 of SW 1 to disable the regen overload alarm. When the regen alarm is disabled, be sure the resistor has enough capacity (after proper derating) to dissipate the regen energy of the load. Refer to section 4.5 of the LEGEND Digital Torque Amplifier SGDG User's Manual for more details.
