Current Profile
When speed control is obtained by field weakening, the ability of the motor to commutate armature current is
reduced at low field currents. Also some motors exhibit commutation limitations at higher speeds even with
rated field current.

Parameter Descriptions
SPD BRK 1 (LOW)
The motor speed at which current limit profiling begins.
Range: 0.00 to 100.00 % (h)
SPD BRK 2 (HIGH)
The upper speed limit at which current limit profiling ends.
Range: 0.00 to 100.00 % (h)
IMAX BRK 1 (SPD1)
This sets the current limit value at or below speed break–point 1, provided the other current limits
are greater than this setting.
Range: 0.00 to 200.00 % (h)
IMAX BRK 2 (SPD2)
This sets the current limit value at or above speed break–point 2, provided the other current limits
are greater than this setting.
Range: 0.00 to 200.00 % (h)
