Preparing for Operation
This section explains the procedure to prepare the Servomotor and Servo Drive for operation on
completion of installation and wiring. It explains items to check both before and after turning ON the
power supply.

Items to Check Before Turning ON the Power Supply
Checking Power Supply Voltage
• Check to be sure that the power supply voltage is within the ranges shown below.
R88D-KP01H/02H/04H/08H/10H/15H (Single-phase or single-phase/3-phase 200 VAC input)
Main circuit power supply: Single-phase or single-phase/3-phase 200 to 240 VAC (170 to 264 VAC)
50/60 Hz
Control circuit power supply: Single-phase 200 to 240 VAC (170 to 264 VAC) 50/60 Hz
R88D-KP20H/30H/50H (3-phase 200 VAC input)
Main circuit power supply: 3-phase 200 to 230 VAC (170 to 253 VAC) 50/60 Hz
Control circuit power supply: Single-phase 200 to 230 VAC (170 to 253 VAC) 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 (
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 side power lines and the power cables must be securely connected.
Checking the Encoder Wiring
• The encoder cable must be securely connected to the encoder connector (CN2) of the Servo Drive.
• The encoder cable must be securely connected to the encoder connector of the Servomotor.
Checking the Control I/O Connector
• The control cable must be securely connected to the control I/O connector (CN1).
• The Operation Command (RUN) signal is OFF.
