• While the default control loop parameter values and the motor type
parameter is loaded the controller signals:
C07_0 Load defaults procedure com. (load controller param.)
• If the parameter values in the encoder data memory cannot be read:
C0706 Error when reading the controller parameters
• If the motor type connected to the controller has changed:
F2008 RL The motor type has changed.
• If an invalid value for the commutation offset is contained in the
encoder memory, the controller signals:
F2104 Commutation offset invalid
The following Rexroth housing motors do not have an encoder data
memory:
• 2AD, ADF
Brief Description
See section "Basics on Rexroth Motors"
The parameters mentioned under "Basics on the Motors to be Controlled"
are used for these motors.
Functional Description
The Rexroth motors without encoder data memory, 2AD, ADF, MAD and
MAF series, are asynchronous motors. Therefore, a value adjusted to the
Motors
application has to be written to the P-0-0532, Premagnetization factor
parameter.
The premagnetization factor influences the "magnetizing current" motor
parameter:
effective magnetizing current = P-0-0532 / 100% * P-0-4004
