Drive Control Mode (B01) is set to the current drive mode at power-up. The user can change the drive mode as follows:
1. Set Pr mm00 to 1253, 1254
2. Change
3. Drive Control Mode (B01) to the required mode
4. Initiate a drive reset
Provided Drive Active (L06) = 0 the drive will change to the new drive mode, and then load and save parameters to non-volatile memory. If Pr mm00
is not set to one of the specified values then the drive mode does not change on drive reset. The value in Pr mm00 determines which defaults are
loaded as follows.
Motor Rated Current (B02) is used as follows:
1. To define the rated operating conditions for motor thermal protection. See Motor Thermal Time Constant 1 (B20).
2. To define the range of the current limits.
3. In the motor control algorithm for Open-loop and RFC-A modes.
