Chapter 12 Trial Operation
Trial operation by the following procedure comes in handy when wiring for positioning or when setting up
system memory.
1 Set the switches on the module.
Set the MODE switch on the module to match the axis to be displayed.
Attach the JW-12/14PS to the rack panel.
Wire the module referring to "Connection method."
Turn the PLC power supply and external power supply (24 VDC) ON. (These power supplies need not
be turned ON simultaneously.)
Assign the special I/O data register (256 bytes) for this module by optional I/O registration.
(Note 1) Automatic I/O registration cannot be used on the JW50H/70H/100H mounted with this
module.
Set parameter 1 (2) by block transfer.
7 Turn the servo driver ON (servo systems only).
Turn only the control power supply of the servo driver ON.
(Note 2) Leave the mains power supply (for motor) OFF.
8 Check and reset any errors.
See "Chapter 13 Troubleshooting."
9 Output clear deviation (servo systems only).
This step is not required if there is no deviation on the driver side.
CAUTION! The following operation causes the motor to operate.
10 Turn the mains power supply ON (servo ON: servo systems only).
A servo lock is applied to the motor if there is an error in the wiring. "Servo lock" refers to the state
where the motor attempts to return to its original state when an external force causes the motor shaft to
rotate.
(Note 3) If the polarities are wired incorrectly on the pulse generator, tachogenerator and motor, the
motor may operate at high speed. Check the wiring again.
4 Turn the PLC and this module ON.
