“ ON ”
●
Poor contact at the CW input
or CCW input
●
Both the CW and CCW
inputs are turned to “ ON ” in
2-pulse input mode
●
The pulse signal is
connected to the DIR input in
1-pulse input mode
●
The CW input and CCW
input are connected in
reverse, when the 2-pulse
input mode is selected
●
The DIR. input is set in
reverse, when the 1-pulse
input mode is selected
●
A geared type is used whose
rotating direction is opposite
that of the motor shaft.
●
Turn the C.OFF input to “ OFF ” and confirm that the
motor windings are excited
●
Check the controller and driver connections
●
Check the pulse signal specifications (voltage, width)
●
Input pulse signal to either the CW input or CCW input
at a time
●
Be sure to turn “ OFF ” the terminal not receiving input
●
Connect pulse signal to the PLS input
( This applies to the
CSD2109-P
,
CSD2112-P
and
CSD2120-P
only )
●
Connect the CW pulse signal and CCW pulse signal to
the CW input and CCW input, respectively
●
Turn the switch “ ON ” when the direction is set to
CW; turn it “ OFF ” when the direction is set to CCW
( This applies to the
CSD2109-P
,
CSD2112-P
and
CSD2120-P
only )
●
The direction rotation of the gear output shaft is
determined by the reduction gear radio. Check the
rotating direction of the gear output shaft of your motor
on page 13.
