Chapter 1 Detail Drive Configuration and Operation
Motor Control
The Motor Control submenu asks you to select the motor control operating
mode which sets the parameter 485 [Motor Ctrl Mode]. Choices are “FOC,”
“FOC2,” “Pmag Motor” and “Test.”
• “FOC” selects field oriented control. This should be the selection for AC
squirrel cage induction motors
• “FOC2” selects field oriented control and is only used for a specific type of
AC induction motor with motor thermal feedback.
• “Pmag Motor” selects control for permanent magnet motors
• “Test” puts the drive in a test mode to perform the direction test. “Test” is
automatically selected during the direction test portion of the Start-Up
routine, and does not need to be set manually by the user.
Next, the motor control submenu prompts you to select whether you have no
dynamic braking, an internal resistor for dynamic braking, or an external resistor
for dynamic braking. When no dynamic braking is selected, the bus regulator is
turned on (see Bus Regulation/Braking on page
20 of this manual for more
details).
Motor Data
This submenu asks you to enter whether the motor power is in units of kW or
HP. Then you are prompted to enter the motor nameplate data. Accurate motor
nameplate data is important for tuning the drive to the connected motor.
Feedback Configuration
The Feedback Configuration submenu asks you to select the feedback device
type. Possible selections are “Encoder 0,” “Encoder 1,” “Aux Speed,” “Motor Sim,”
or “Option Card.” Encoder 0 and Encoder 1 are for the encoders on the I/O
board. When “Encoder 0” or “Encoder 1” are selected, you must also enter the
encoder ppr. “Motor Sim” is to simulate a motor when there is no motor
connected to the drive. “Option Card” can be chosen when either the Resolver or
Hi-Resolution Encoder option cards are installed.
Power Circuit Test
This submenu allows you to perform a diagnostic check to check the output
section of the drive power circuit for shorts or open circuits.
