Product Detail

GK800 Closed-loop Vector Control Variable Speed Drive

GK800 Series High Performance Variable Speed Drives, adopting most advanced close-loop vector control technology, are able to perform precise control on both asynchronous motors and permanent magnet synchronous motors. GK800 series, one of the real drives leaders, are superb in demanding applications with excellent performance no matter in speed control, torque control, position control, field weakening control, or response time, and so on.

GK800 supports position control, with expansion boards of EPC-PG1 and EPC-PG2 available. For detailed instructions of the expansion boards, please email me or download from our website.

EPC-PG1: Support open collect, and push-pull encoder signal input, with power supply 12V. Support A/B/Z signal open collector frequency dividing output (applicable for asynchronous motor only) 

EPC-PG2: Support open collector, push-pull, and differential encoder signal input, with power supply 5V/12V programmable. Support A/B/Z signal frequency dividing output, i.e. A+/A-, B+/B-, Z+/Z- (applicable for asynchronous motor only)

For position control, please see the parameters below: For details, please refer to GK800 user manual.
