3-41 Ramp 1 Ramp Up Time
Default value: Size related
Setup: All setups
Data type: Uint32
Enter the ramp-up time, that is the acceleration time from 0 RPM to the synchronous motor speed n
prevents the output current from exceeding the current limit in parameter 4-18 Current Limit during ramping. The value 0.00
corresponds to 0.01 s in speed mode. See ramp-down time in parameter 3-42 Ramp 1 Ramp Down Time.
3-42 Ramp 1 Ramp Down Time
Default value:
Size related
Setup: All setups
Data type:
Uint32
Enter the ramp-down time, that is the deceleration time from the synchronous motor speed n
that no overvoltage occurs in the inverter due to regenerative operation of the motor, and such that the generated current does not
exceed the current limit set in parameter 4-18 Current Limit. The value 0.00 corresponds to 0.01 s in speed mode. See ramp-up time in
parameter 3-41 Ramp 1 Ramp Up Time.

3-51 Ramp 2 Ramp Up Time
Default value:
Size related
Setup: All setups
Data type:
Uint32
Enter the ramp-up time, that is the acceleration time from 0 RPM to the nominal motor speed ns. Select a ramp-up time such that the
output current does not exceed the current limit in parameter 4-18 Current Limit during ramping. The value 0.00 corresponds to 0.01 s in
speed mode. See ramp-down time in parameter 3-52 Ramp 2 Ramp Down Time.

Default value:
Size related
Setup: All setups
Data type:
Uint32
Enter the ramp-down time, that is the deceleration time from the nominal motor speed n
no overvoltage occurs in the drive due to regenerative operation of the motor, and such that the generated current does not exceed the
current limit set in parameter 4-18 Current Limit. The value 0.00 corresponds to 0.01 s in speed mode. See ramp-up time in parameter
3-51 Ramp 2 Ramp Up Time.
