Preparing for Operation

This section explains the procedure following installation and wiring of the Servomotor
and Servo Driver, to prepare the mechanical system for operation. It explains what you
need to check both before and after turning ON the power. It also explains the setup pro-
cedure required if using a Servomotor with an absolute encoder.

4-2-1 Turning Power ON and Checking Indicators

H Items to Check Before Turning ON the Power
D Checking Power Supply Voltage
• Check to be sure that the power supply voltage is within the ranges shown below.
R88D-WTjHL (Single-phase 100 V AC input)
Main-circuit power supply:
Control-circuit power supply: Single-phase 100/115 V AC (85 to 127 V) 50/60 Hz
R88D-WTA3H/A5H/01H/02H/04H (Single-phase 200 V AC input)
Main-circuit power supply:
Control-circuit power supply: Single-phase 200/230 V AC (170 to 253 V) 50/60 Hz
R88D-WT05H/08H/10H/15H/20H/30H/50H/60H/75H/150H (Three-phase 200 V AC input)
Main-circuit power supply:
Control-circuit power supply: Single-phase 200/230 V AC (170 to 253 V) 50/60 Hz
D Checking Terminal Block Wiring
• The main-circuit power supply inputs (L1/L2 or L1/L2/L3) and the control-circuit power supply inputs
(L1C/L2C) must be properly connected to the terminal block.
• The Servomotor's red (U), white (V), and blue (W) power lines and the yellow/green ground wire ( )
must be properly connected to the terminal block.
D Checking the Servomotor
• There should be no load on the Servomotor. (Do not connect to the mechanical system.)
• The power lines at the Servomotor must be securely connected.
D Checking the Encoder Connectors
• The Encoder Cable must be securely connected to the Encoder Connector (CN2) at the Servo Driv-
er.
• The Encoder Cable must be securely connected to the Encoder Connector at the Servomotor.
D Checking the Control Connectors
• The Control Cable must be securely connected to the I/O Control Connector (CN1).
• The RUN command (RUN) must be OFF.
