No. Signal name Item Contents
1
SVALM
INPOS
SVRDY
[Input circuit form]
These signals are input from
the servo driver.
2
EXTPOW
[+24V power supply connection
for servo I/F]
Normally, connected to the ex24V terminal of the servo driver.
3
SVALM [Servo Alarm]
Signal polarity is set by G9003 initial setting (RENV1-b9) (Initial value: NC)
4
INPOSition [Positioning completion (coin)]
Signal polarity is set by G9003 initial setting (RENV1-b22) (Initial value: NC)
5
SVRDY
[Servo ready]/[PCS]
See the next page, Note 1.
Signal polarity is set by G9003 initial setting (RENV1-b24) (Initial value: NC)
Also, when using SVRDY, the mode register initial setting must be set to:
RMD-
b13 = ‘0’.
6 SVBRK
[Using brake release signals]
See the next page, Note 1.
As for brake release signals (SVBRK), refer to the document for the driver to
be used.
[Circuit form]
Only transmits release signals
from the servo to the machine
I/F connector.
Note: Driving current for the electromagnetic brake depends on the driver’s
performance. However, the maximum is 50mA based on the
allowable current value for the module power supply circuit.
