6-2 Preparing for Operation
This section explains the procedure for preparing the mechanical system for operation following
installation and wiring of the Servomotor and Servo Drive. It explains what you need to check both
before and after turning ON the power.
It also explains the setup procedure required for using a Servomotor with an absolute encoder.
Items to Check Before Turning ON the Power
 Checking Power Supply Voltage
 Check to be sure that the power supply voltage is within the ranges shown below.
R88D-GTL-ML2 (single-phase 100 VAC input)
Main circuit power supply: Single-phase, 100 to 115 VAC (85 to 127 V), 50/60 Hz
Control circuit power supply: Single-phase, 100 to 115 VAC (85 to 127 V), 50/60 Hz
R88D-GN01H-ML2/02H
-ML2/04H-ML2/08H-ML2/10H-ML2/15H-ML2
(Single-phase or single/three-phase 200 VAC input)
Main circuit power supply: Single-phase or single/three-phase, 200 to 240 VAC
(170 to 264 V), 50/60 Hz
Control circuit power supply: Single-phase or single/three-phase, 200 to 240 VAC
(170 to 264 V), 50/60 Hz
R88D-GN20H
-ML2/30H-ML2/50H-ML2/75H-ML2 (three-phase 200VAC input)
Main circuit power supply: Three-phase, 200 to 230 VAC (170 to 253 V), 50/60 Hz
Control circuit power supply: Single-phase, 200 to 230 VAC (170 to 253 V), 50/60 Hz
 Checking Terminal Block Wiring
 The main circuit power supply inputs (L1/L3 or L1/L2/L3) must be properly connected to the
terminal block.
 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 green/yellow ground wire
( ) must be properly connected to the terminal block.
 Checking the Servomotor
 There should be no load on the Servomotor. (Do not connect the mechanical system.)
 The Servomotor's power lines and the power cables must be connected securely.
 Checking the Encoder Connectors
 The Encoder Cable must be connected securely to the Encoder Connector (CN2) at the Servo
Drive.
 The Encoder Cable must be connected securely to the Encoder Connector at the Servomotor.
 Checking the Control I/O Connectors
 The Control Cable must be connected securely to the Control I/O Connector (CN1).
 The RUN command (RUN) must be OFF.
 Checking Parameter Unit Connections
 When using the Parameter Unit (R88A-PR02G), the enclosed cable must be connected securely
to the CN3 connector.
