…Feedback Options, continued:
Stepper Amplifiers Only
Motor Encoder
Select the encoder type:
None
Primary incremental
Run in Servo Mode
(With encoder only.) Amplifier operates as a true, closed loop, servo
amplifier controlling a stepper motor.
Enable Encoder
Correction
(With encoder only.) Amplifier runs as a stepper drive; encoder
feedback is used to correct positional errors. See Encoder Correction
(p. 142).
For more information see Motor/Feedback (p. 41).
4.4: Operating Mode Options
View or change the settings described below. Options vary with amplifier model.
Setting
Description
Operating Mode
Choose the mode of operation: Current, Velocity, or Position.
See Servo Operating Modes and Control Loops (p. 11).
Command Source
Choose the command input source:
Analog Command: Analog voltage provides command input.
See Command Inputs (p. 69).
PWM command (current and velocity mode only): Digital pulse-width
modulated signal provides command input.
See Command Inputs (p. 69).
Function Generator: Internal function generator provides command
input.
Software Programmed: The amplifier is controlled by software
commands from either the Copley Virtual Machine (CVM) or an external
source. See Copley Indexer Program User’s Guide or the Copley ASCII
Interface Programmer’s Guide.
Camming: Runs in Camming Mode. See Copley Camming User Guide.
Digital Input: Command input is provided via the chosen Input Source
(below). See Digital Position Input Settings (p. 76).
CAN: Command input is provided over the CANopen network. See the
CANopen Programmer’s Guide.
Input Source
Choose the input source for PWM or Digital input commands:
Single-ended Inputs: Command input is provided via two of the
amplifier’s programmable digital inputs.
Multi-mode Port: Command input is provided via differential inputs on the
amplifier’s multi-mode port.
Differential Inputs: Command is provided via differential inputs.
High Speed Inputs. Command is provided via two of the amplifier’s high
speed inputs.
