AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
To control the brake forcibly via EtherCAT communications, set Digital outputs - Physical outputs
(60FE-01 hex) and Function Output - Bit Mask (4602-01 hex). However, to prevent a workpiece from
falling for a vertical axis, the brake is constantly applied except when the status of ESM is Operational.
Relationship between Brake Interlock Function and Status of ESM
Set External Brake Interlock Output - Port Selection (4663-01 hex) to change the output port of
the brake interlock signal.
The following table lists output ports corresponding to values of Port Selection.
You can monitor the output status of the brake interlock signal by I/O Monitor - Physical I/O
(4600-81 hex), Digital inputs (60FD-00 hex) bit 26, and External Brake Interlock Output - Signal
Status (4663-81 hex).
The output status is given to data that are indicated with a check mark in the following table.
