High accuracy and quality waveform. PMC function

PMC function* (Factory option)
Pulse motor control function SG-507 (SG-4115)
Pulse motor control function SG-506 (SG-4105)

Pulse outputs in open collector (50V) are output from rear panel with PMC option. Common motor driver circuit connected with PMC
  PMC option function controls pulse motor. Pulse motor is evaluated acceleration or braking controls not only by position control, but also under loaded condition. The PMC option makes ease the evaluation.

  *PMC (Pulse Motor Control) is coined word by IWATSU.
Upper waveform shows drive pulse for pulse motor, lower waveform shows sensor input waveform. After reaching maximum frequency while specified accelerating period, starts braking by sensor input signal. Then stops at specified pulse counts.SG-4115 can CW/CCW repeat control with 2 channel output signals.

Extended external modulation (Option)
External modulation is available for any kind of modulation.
Below shows liquid temperature control system by controlling heater power with PWM.<Example>

  Example of PWM external modulation
(Note: These waveforms are for helping to understand PWM, not actual waveform of below example.

Upper waveform:20-30% modulated PWM waveform
Lower waveform: External modulation input waveform
