Sequence Input (2 Inputs)

Servo ON, P drive (or motor forward/reverse by

zero-clamp drive reference, or contact input

speed control), alarm reset, current limit (select

from parameters)

Sequence Output (2 Outputs) Current limit detection,TGON, speed

coincidence, external brake interlock, servo

alarm (servo alarms are fixed, other settings are

selected from parameters)

Protective Functions

Overcurrent, overload, overspeed, reference

input read error, overrun prevention, CPU error,

encoder error

Indicators

LED indicators

Red: Alarm, Green: Ready

Others

Torque control, zero-clamp operation (position

loop stop), soft start/stop, speed coincidence,

brake interlock signal output, JOG run,

autotuning

*

1

Use within the ambient temperature range. When enclosed in a box, the internal tem-
peratures must not exceed the ambient temperature range.

*

2

The lowest speed of the speed control range is the speed at which the motor does not
stop under 100% load.
