Function
Inputting this signal makes the SERVOPACK ready to receive speed reference input
Base block and dynamic brake are cleared
Proportional control reference applies friction torque to the motor to prevent
drifting when the motor is left motionless without reference input while the
main circuit is kept energizec
In the case of linear drive etc . connect limit switch signal according to the run
direction T h i s signal is "closed" during normal run
When limit switch is tripped, it becomes "open "
External power supply to 1 CN-8, 24 26. 41 and 43
Prepare a 24VDC(25mA min) power supply
At ± 6 OV, ± rated speed is obtained
At ± 2 0 to ± 1 0 0 V. ±rated speed is obtained
For adjustment potentiometer I IN-B i s used

This signal resets the alarm
Table 5 5 O u t p u t Signals of Connector 1 CN
Function
Turns OFF when fault is detected
For details refer to Table 6 2, "Fault Detection Function "
Turns ON when motor speed exceeds approx 45 r/min or 450 r/min
The motor speed can be changed by using SW1-3
• 45 r/min --• Short-circuit SW1-3
• 450 r/min •• Open SW1-3
• N-CL or P-CL used T u r n > ON when output torque reaches the level set by
• N-CL or P-CL not used T u r n s ON when output torque reaches the level
Turns ON when main power supply ON. and no servo alarm
