J7 Drive
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.
