Standard Ramp with High Motor Voltage
Parameter 2.04 = 2
This mode works in exactly the same way as standard ramp with normal motor voltage. The only difference is that the drive
will allow the motor rated voltage to rise to 1.2 times the programmed motor rated voltage. This increase in motor voltage
increases the losses in the motor, therefore reducing the amount of regenerated energy flowing back into the drive.
Increasing the losses in the motor and reducing the amount of regenerated energy flowing back into the drive will reduce the
deceleration ramp time when compared to standard ramp with normal motor voltage for a given amount of regenerated
energy.
12.29 Stopping Modes
On Commander SE, there are 5 stopping modes - parameter 6.01:
• Coast to stop
• Ramp to stop
• Ramp to stop + timed DC injection braking
• Injection braking stop with detection of zero speed
• Time DC injection braking stop
The drive will enter one of the above stopping modes when the enable, run forward, run reverse, run or not stop terminals
are opened, depending on the programmed terminal configuration.
When the enable terminal is opened, the drive will always enter the coast to stop mode.
There is a delay of 65ms in the drives software when switching from run forward to run reverse or vice-versa. This
delay is to allow the direction of motor rotation to be changed without the drive entering one of the above selected
stopping mode.
During each of the stopping mode sequences, there are two distinct phases:
• decelerating to stop
• stopped
Mode 1: Coast to stop
Parameter 6.01 = 0
Phase 1
The output bridge of the drive is disabled.
Phase 2
The drive cannot be re-enabled for 2 seconds.
The 2 seconds delay in phase 2 allows the rotor flux to decay before the drive is allowed to be re-enabled. This 2 second time
cannot be adjusted.
