Parameter Settings
60.08
Frequency Point for
DC Braking
Range: 0.0 to 60.0 Hz Default: 0.0
Unit: 0.1 Hz
This parameter determines the Frequency Point for DC
Braking to begin upon a stop command.
Figure 5-46: DC Braking
Note: DC Braking during Start-Up is used for loads that may
move before the AC drive starts, such as fans and pumps.
These loads may also be moving in the wrong direction.
Under such circumstances, DC Braking can be executed to
hold the load in position before applying a forward motion.
DC Braking during stopping is used to decrease stopping time
and also to hold a stopped load in position. For high inertia
loads, a dynamic braking resistor may be needed for quick
decelerations.
60.09
Torque Compensation Range: 00 to 10% Default: 00%
Units: %
This parameter selects the % of increased voltage upon
acceleration of the AC drive. This is helpful during start-up to
obtain a higher initial starting torque. Increased voltage to the
motor also increases current and heat. Always start with a
low Torque Compensation value and slowly increase until
sufficient starting torque is achieved.
This parameter may be set during operation.
