3. SIGNALS AND WIRING

3.3.2 Signal explanations

For the I/O interfaces (symbols in I/O column in the table), refer to Section 3.6.2. In the control mode field of the table

P : Position control mode, S: Speed control mode, T: Torque control mode : 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 43 to 49.

The pin No.s in the connector pin No. column are those in the initial status.

amplifier ready to operate (servo-on).

Disconnect SON-SG to shut off the base circuit and coast the

servo motor (servo off) .

Set "

1" in parameter No. 41 to switch this signal on

(keep terminals connected) automatically in the servo

amplifier.

Reset

RES

CN1B

Disconnect RES-SG for more than 50ms to reset the alarm.

Some alarms cannot be deactivated by the reset signal. Refer to

Section 10.2.

Shorting RES-SG in an alarm-free status shuts off the base

circuit. The base circuit is not shut off when " 1 " is set in

parameter No. 51.

Forward rotation

LSP

CN1B

To start operation, short LSP-SG and/or LSN-SG. Open them to

bring the motor to a sudden stop and make it servo-locked.

Set "
