Option
Analog output (3 sets). Alarm output. External operation input.
Note (
15
) If this unit directly measures an inverter output of cycle control, SCR phase angle control or PWM
control, an error may increase due to its operation principle.
Note (
16
) Analog output, alarm output and external operation input are options.
