3.2 Y1, Y2, Y3 and Y4 Digital Outputs
• Y1 can be used as an alarm signal output. It can also be used as a static in position signal
output (static, checking in position when the motor is stopped), or as a dynamic in position signal
output (dynamic, checking in position all the time).
• Y2 can be used as a tach signal output. Tach output produces pulses relative to the motor
position with congurable resolution. It can also be used as a static in position signal output
(static, checking in position when the motor is stopped), or as dynamic in position signal output
(dynamic, checking in position all the time), or as a timing signal output (50 pulses per rotation).
• Y3 can be used as a signal output to release a brake. It can also be used as a static in position
signal output (static, checking in position when the motor is stopped), or as a dynamic in position
signal output (dynamic, checking in position all the time).
• Y4 can be used as a static in position signal output (static, checking in position when the motor
is stopped), or as a dynamic in position signal output (dynamic, checking in position all the time).
Use Step-ServoQuickTuner software for Y1, Y2, Y3 and Y4 function conguration.
The following graphs show some common connection methods for the outputs:
NOTE: Do not connect the outputs to more than 30VDC power supply. And the
current of each output terminal must not exceed 100mA.
