Measurement of release delay time and braking delay time
The value of release delay time and braking delay time are measured by the circuit below.
 Varistor used circuit
 Diode used circuit
 When using CNE holding brake output which is built in servo amplifier (400VAC)
* For use of holding brake power supply built in servo amplifier, brake power voltage may drop by
influence of cable impedance. Make sure the voltage at power plug of motor is 21.6 VDC or more.
If it is less than 21.6 VDC, adjust control power voltage up to 26.4 VDC and check the voltage
again.
