3.14 SAFETY BRAKE SIGNAL OUTPUT FUNCTION
The CNC and the SV output the Safety Brake signal (*BRKx) to
control the mechanical brake. When this signal is “0”, mechanical
brake must be activated. When this signal is “1”, mechanical brake is
allowed to be released.
These signals cannot be used with the ignore v-ready off for all axes
signal <G
n
066#0> and the ignore v-ready off for each axis <G
n
192> at
the same time.
When the inconsistency between the break signal on PMC and that on
DCS PMC is lasted for the time that is specified by the parameter
No.1945, the safety function sets MCC Off signal (*DCALM) to “0”
and generates the alarm “safe I/O cross check error”
(PW0010/PW0011).
