Limit Input Operations
Section 7-5
Note
The maximum rotation speed depends on the Servomotor used. Refer to the
maximum momentary rotation speed for the Servomotor used. The following
values apply to W-series Servomotors.
3,000-r/min Servomotor (cylinder type or flat type): 5,000 r/min
1,000-r/min Servomotor: 2,000 r/min
1,500-r/min Servomotor (450 W to 7.5 kW): 3,000 r/min
1,500-r/min Servomotor (11 to 15 kW): 2,000 r/min

Limit Input Operations
The PCU uses the Servo Drive's internal forward drive prohibited signal input
and reverse drive prohibited signal input as the forward rotation limit input sig-
nal and reverse rotation limit input signal, respectively. Additionally, the for-
ward/reverse software limits can be used by setting the Servo Parameters.
The stop operation when the forward/reverse rotation limit input signal is input,
and the forward/reverse software limit is reached depend on the Servo Param-
eter settings, as shown in the following table.
1. This operation occurs when a limit input signal is input in the direction opposite to the
travel direction due to incorrect wiring or other cause.
2. For details on software limit functions, refer to

Limit input sig-
nal
The Servomotor operation is stopped
at the Servo Drive according to the set-
ting of Servo Parameter Pn001.1
(Pn504 for G5 Series, Pn004 for G
Series).
At the PCU, a limit input error occurs,
causing an emergency stop, except
when using the origin search opera-
tion's reversal mode.
An emergency stop
caused by a limit input
error is executed at the
PCU, except when exe-
cuting ORIGIN SEARCH.
Software limit
The Servomotor operation is stopped
at the Servo Drive according to the set-
ting of Servo Parameter Pn001.1
(Pn504 for G5 Series, Pn004 for G
Series). (See note 2.)
At the PCU, a software limit error
occurs, causing an emergency stop.
