(4) Signal explanations
In the Control Mode field of the table
: Denotes that the signal may be used in the initial setting status.
: Denotes that the signal may be used by setting the corresponding parameter among
parameters No. 1 and 43 to 49.
The pin No. in the connector pin No. column is the number under initial status.

Functions/Applications
No.
CN1B
Connect SON-SG to switch on the base circuit and make
5
the servo amplifier ready to operate (servo on).
Disconnect SON-SG to shut off the base circuit (servo off)
andcoast the servo motor.
Set
1 in parameter No. 41 to switch this signal on
(keep terminals connected) automatically in the servo
amplifier.
CN1B
Disconnect RES-SG for more than 50ms to reset the alarm.
14
During alarm resetting, the base circuit is shut off.
The following alarms cannot be reset:
Dis-

A. 11
Board error 1
A. 12
Memory error 1
A. 13
Clock error
A. 15
Memory error 2
A. 16
Encoder error 1
A. 17
Board error 2
A. 18
Board error 3
Also, the regenerative error (A. 30) and overload 1 (A. 50)
cannot be reset until the regenerative brake resistor and
power transistor are cooled to proper temperatures, respectively.
If the line between RES and SG is short-circuited during the
operation and no alarm is given, the status will come to the base
and the servo motor will freely run to a stop.
CN1B
The forward and/or reverse rotation stroke end signal must
16
be ON to run the servo motor. If the signal is switched off,
the servo motor will stop suddenly and servo-locked. By
setting
1 in parameter No. 22, the servo motor will
come to a slow stop when the signal is switched off.
Relationships between signal status and operation are as
follows:
