J7 Drive

1/8 - 5 HP

The J7 drive was a general purpose AC drive; its PWM design provided low motor noise and high starting torque, with a current overload rating of 150% for 60 seconds. V/f control made this drive suitable for most general applications. The J7 was feature-packed, low cost, and compact. The digital operator included a 3-digit LED status display. Digital programming covered 79 parameters. The J7 had five digital inputs (3 progammable), 1 analog input, and 1 digital output (programmable). An optional RS-485 Modbus RTU serial communication port was available. An ideal choice whenever low cost and small size were required.

The J7 Drive is a Legacy product and is no longer promoted in the Americas. Earlier versions of this product were named GPD 305/J7, GPD 305, or VS Mini J7.

	Question	Posted Date
	How do I enter the Run Command from the control circuit terminals? Posted Date: 11/28/2005 Answer: The Run command Method is entered from the digital operator when at factory settings. Change the Run Command Selection parameter n02 to "1" to enter the Run Command from the control circuit terminal. Refer to TM.J7.01 for more information.

	How can the gain be changed for an Analog Input? Posted Date: 09/13/2012 Answer: The gain can be changed by setting in the Analog Frequency Command Gain parameter, n041. Other bounds can be set on the reference by configuring the Bias parameter, n042. Please refer to TM.J7.01 for more information.

	Does installation of an AC Drive near a large capacitor bank (power-factor correction) require special consideration? Posted Date: 10/27/2005 Answer: Yes. Capacitors are put across the AC power line to correct for lagging power factor due to inductive loads. Motors, relay coils, transformers, etc. are inductive loads. Many times capacitors are switched on and off the line as demand changes. Unfortunately, this switching results in large voltage spikes on the power line which can damage the drives rectifier circuit. To prevent damage use a 5% line reactor on the drive's input. If overvoltage faults are indicated, add dynamic braking -- this will clamp the DC bus.

	Can the J7 Drive be used with a single-phase, 100V input? Posted Date: 11/28/2005 Answer: There is no single-phase, 100V input type for the J7 Drive. Please use the VS Mini C-Series (0.1 - 0.75kW). See Table A2-1 in TM.J7.01 for a list of the J7 Drive power supply specifications. Note: Earlier versions of the J7 Drive were named GPD 305/J7, GPD 305 or VS Mini J7.

	Can a Dynamic Braking resistor be installed on a J7 Drive? Posted Date: 10/11/2004 Answer: The J7 Drive does not have an internal braking transistor therefore that option can not be installed. An separate braking module is be needed. It may be more cost effective to use a V7 Drive instead for that application. Note: Earlier versions of the J7 Drive were named GPD 305/J7, GPD 305 or VS Mini J7 and earlier versions of the V7 Drive were named GPD 315/V7, GPD 315 or VS Mini V7.
