DESCRIPTION

Built-in PID Control for easy direct integration.
Built-in PID controls temperature, pressure, etc. through the proportional, integral and differential calculus between thye feedback value and reference value in closed loop.

Built-in Communication Interface
The GS series integrates popular communication interfaces such as Modbus-RTU, and RS232/485.

Optimum Acceleration and Deceleration
Trip-free mode achieves maximum torque during accel/deceleration.  The 32-bit DSP CPU monitors the current transition to program an optimum curve below trip-triggering levels.
