7.4.1 Preparing the Servomotor for Trial Operation
This section provides the procedure to prepare the Servomotor for trial operation.
Preparations
Always confirm the following before you perform the procedure to prepare the Servomotor for
trial operation.
• Make sure that the preparations given in 7.1 Flow of Trial Operation on page 7-2 have been
completed.
• Make sure that the trial operation described in 7.3 Trial Operation for the Servomotor without
a Load on page 7-7 has been completed.
Operating Procedure
The following procedure assumes that the default settings are used for the I/O signals required
for trial operation. Refer to the following section for information on the default I/O signal set-
tings.
4.2 Basic Wiring Diagrams on page 4-9
1. Wire the I/O signals from the host controller.
Refer to the following section for details.
4.2 Basic Wiring Diagrams on page 4-9
2. Check the following items.
 Make sure that the /S-ON (Servo ON) signal can be input.
 Make sure that the P-OT (Forward Drive Prohibit) and N-OT (Reverse Drive Prohibit)
signals are ON (closed).
Setting Procedure
• Input the signal to turn ON CN1-42 and CN1-43 (closed).
• Set Pn50A to n.8 (Set the signal to always enable forward drive) and Pn50B to
n.8 (Set the signal to always enable reverse drive).
CAUTION
 Before you perform trial operation of the Servomotor without a load for references from the
host controller, make sure that there is no load connected to the Servomotor (i.e., that all
couplings and belts are removed from the Servomotor) to prevent unexpected accidents.
