Brake Timing: Sequence Output Signal (Reference Value 14) - Fuji Electric Alpha7 VV User Manual

Brake timing: Sequence output signal (Reference value 14)

The timing signal for applying or releasing the brake of the servomotor.
The signal is turned on during operation, while it is turned off after operation is stopped.
 Function
The brake timing output is turned off if the servo-on [S-ON] signal is turned off. The operation
preparation complete [RDY] signal turns OFF once the brake holding time (PA2_64) has elapsed.
 Parameter setting
To assign the brake timing output to a sequence output terminal, specify the corresponding value
("14") to the output terminal function setting parameter.
The brake timing is issued at the specified OUT terminal.
This signal is handled to be always turned off if it is not assigned to the sequence output terminal.
Use a relay or solid state relay (SSR) as the brake cannot be released directly in the sequence
output terminal (DC+30V/50mA).
 The brake attached to the servomotor is "for retention."
Do not use it for braking.
 Do not use the 24 [V] power supply for sequence I/O signals in parallel.
Be sure to prepare a separate power supply for the brake.
 To apply or release the brake with the brake timing output, turn the servo-on
[S-ON] signal off first before turning the power off.
