The figure below shows the part names for servo amplifiers.
Version Number
Indicates the Servo Amplifier hardware version and
software version (See "Amplifier Version Number").
Chapter 1: Checking Product and Part Names
Battery Holder
Used to house the backup battery for an
absolute encoder.
CN5 Analog Monitor Connector
Used to monitor motor speed, torque refer-
ence, and other values through a special cable.
CN8 Battery Connector
Used to connect to the backup battery for an
absolute encoder.
Panel Display
Five-digit 7-segment display panel used to
show servo status, alarm status, and other
values when parameters are entered.
Panel Keys
Used to set parameters.
Power ON Indicator
Lights when the control power supply is ON.
Charge Indicator
Lights when the main circuit power supply is
ON and stays as long as that component's
capacitor remains charged. Therefore, if this
indicator is ON, do not touch the servo
amplifier, even after the power supply is
turned OFF.
CN10 Connector for Option Unit
Connects option units for expanding the amplifier's functions.
CN3 Connector to PC or Digital Operator
Used to communicate with a personal computer or to
connect to an optional digital operator.
CN1 I/O Signal Connector
Used for both reference input and sequence I/O signals.
Nameplate
Indicates the servo amplifier model and its specific ratings.
CN2 Encoder Connector
Connects to the encoder in the servomotor.
Ground Terminal
Must be connected to protect against electrical shock.
Main Circuit Power Supply Terminal
Used for the main circuit power supply input.
Control Power Supply Terminal
Connects to the control power supply and to externally
mounted regenerative resistor (where applicable).
Servomotor Terminal
Connects to the servomotor power line.
