15.2.4 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
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.

CN1 To start operation, short LSP-SG and/or LSN-SG. Open them to
6 bring the motor to a sudden stop and make it servo-locked.
Set " 1" in parameter No. 22 to make a slow stop.

Set parameter No. 41 as indicated below to switch on the signals
(keep terminals connected) automatically in the servo amplifier:

Turn TL off to make Internal torque limit 1 (parameter No. 28)
valid, or turn it on to make Analog torque limit (TLA) valid.
For details, refer to (1)(C), Section 15.2.5.
When using this signal, make it usable by making the setting of
parameter No. 43 to 48.
(Refer to (5), Section 3.4.1.)
