Note
•
When using the TIM output, stop the motor’s output shaft at an integer
multiple of 7.2°.
•
When switching the step angle, do this with the motor stopped and the
TIM output ON.
•
When the power is turned ON, the excitation sequence is reset to STEP
0 and the timing signal is output.

The section indicates that the photocoupler diode is emitting light.
∗1
“100 µs or more” indicated in connection with the direction-signal select time (1-pulse
input mode) or CW/CCW pulse select time (2-pulse input mode) indicates a circuit
response time. Set it to the time required for the motor to respond to the applicable pulse
input.
∗2
The specific duration varies depending on the load inertial moment, load torque,
self-starting frequency, etc.
∗3
Do not input pulse signals immediately after switching the AWO input to OFF, given that it
will affect the motor’s starting characteristics.
∗4
After turning off the power supply, wait at least 5 seconds before turning the power supply
back on.

The

,
CSD2145T
supports a 1-pulse input mode only.
Note
The
CSD2109-T
,
CSD2112-T
, and
CSD2120-T
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).
