6-2 Preparing for Operation
This section explains the procedure to prepare the mechanical system for trial operation after the
installation and wiring of the Servomotor and Servo Drive are completed. It also explains the items
that need to be checked before and after turning ON the power.
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-BP
@@
L (Single-phase 100 VAC input)
Main-circuit power supply: Single-phase 100/115 VAC (85 to 127 V) 50/60 Hz
R7D-BP
@@
H (Single-phase/three-phase 200 VAC input)
Main-circuit power supply: Single-phase/three-phase 200/240 VAC (170 to 264 V) 50/60 Hz
R7D-BP

HH (Single-phase 200 VAC input)
Main-circuit power supply: Single-phase 200/240 VAC (170 to 264 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 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 are securely connected.
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 I/O Control Connectors
The Control Cable must be securely connected to the I/O Control Connector (CN1).
The RUN Command Input (RUN) must be OFF.
Checking Parameter Unit Connections
The Parameter Unit (R88A-PR02G) must be securely connected to the CN3 connector.
Turning ON Power
After checking the above items, turn ON the main circuit power supply.
The alarm output (ALM) will take approximately 2 seconds to turn ON after the power has been
turned ON. Do not attempt to detect an alarm using the Host Controller during this time (when
power is being supplied with the Host Controller connected).
