6-2 Preparing for Operation
This section explains the procedure to prepare 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 if 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 (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-GT01H/02H/04H/08H/10H/15H (single-phase or single-phase/three-phase 200 VAC input)
Main-circuit power supply: Single-phase or single-phase/three-phase 200 to 240 VAC
(170 to 264 V), 50/60 Hz
Control-circuit power supply: Single-phase or single-phase/three-phase 200 to 240 VAC
(170 to 264 V), 50/60 Hz
R88D-GT20H/30H/50H/75H (three-phase 200 VAC 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 input lines (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 securely connected.
Checking the Encoder Connectors
• The Encoder Cable must be securely connected to the Encoder Connector (CN2) at the Servo
Drive.
• The Encoder Cable must be securely connected to the Encoder Connector at the Servomotor.
Checking the Control I/O Connectors
• The Control Cable must be securely connected to the Control I/O Connector (CN1).
• The RUN Command Input (RUN) must be OFF.
Checking Parameter Unit Connections
• When using the Parameter Unit (R88A-PR02G), the enclosed cable must be securely connected
to the CN3B connector.
