s is shown as a response time of circuit. The motor may
need more time.

2. Depends on load inertia, load torque, and starting frequency.

3. Do not input pulse signals immediately after switching the C.OFF input to “OFF”, given that it will
affect the motor’s starting characteristics.

4. Wait at least 5 seconds before turning on the power.
The
CSD2109-P
,
CSD2112-P
, and
CSD2120-P
respond up to 10 kHz with a pulse duty of 50%.
When using it at higher speeds, narrow the pulse
width (shorten the photocoupler’s ON time).
