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.
