*2: Delay time from the moment BRK_OFF signal is given until actual holding brake is
released or BRK_ON signal is given until actual holding brake is activated. It is
dependent on the holding brake of the motor.
*3: Deceleration time is determined by Pr6.14 or if motor speed goes below Pr4.39,
whichever comes first. BRK_OFF given after deceleration time.
*4: Pr4.37 set time value.
Delay time from the moment SRV_ON is given until BRK_OFF switch to BRK_ON, is
less than 500ms.

To set the activation speed for which holding brake will be activated.
When SRV-OFF signal is given, motor decelerates, after it reaches below Pr4.39 and Pr6.14 is not
yet reached, BRK_OFF is given.
BRK_OFF signal is determined by Pr6.14 or if motor speed goes below Pr4.39, whichever comes
first.
Application:
1. After disabling axis, Pr6.14 has been reached but motor speed is still above Pr4.39, BRK_OFF signal
given.
2. After disabling axis, Pr6.14 has not been reached but motor speed is below Pr4.39, BRK_OFF signal
given.

To set command pulse count per revolution for second motor.
Switch with Pr0.08 by using I/O interface frequency divider/multiplier switching input signal DIV1
1. When Pr5.00
≠
0 : Motor revolution = Pulse count input / Pr5.00
2. When Pr5.00 = 0: Actual position pulse count is limited by Pr5.01 and Pr 5.02.
