4-3 Preparing for Operation
This section explains the procedure following installation, wiring, and switch setting of
the Servomotor and Servo Driver, to prepare the mechanical system for trial operation.
It explains what you need to check both before and after turning ON the power.
4-3-1 Turning Power ON and Checking Indicators
■ 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.
R7D-AP@L (Single-phase 100-V AC input)
Main-circuit power supply: Single-phase 100/115 V AC (85 to 127 V) 50/60 Hz
Control-circuit power supply: Single-phase 100/115 V AC (85 to 127 V) 50/60 Hz
R7D-AP@H (Single-phase 200-V AC input)
Main-circuit power supply: Single-phase 200/230 V AC (170 to 253 V) 50/60 Hz
Control-circuit power supply: Single-phase 200/230 V AC (170 to 253 V) 50/60 Hz
R7D-AP08H (Three-phase input)
Main-circuit power supply: Three-phase 200/230 V AC (170 to 253 V) 50/60 Hz
Control-circuit power supply: Single-phase 200/230 V AC (170 to 253 V) 50/60 Hz
● 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.
● 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.
• The Encoder Cable must be securely connected to the Encoder Connector (CN2) at the Servo
Driver.
• The Encoder Cable must be securely connected to the Encoder Connector at the Servomotor.
● 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.
