Function DC: DC brake voltage
TAB1
This parameter controls the amount of DC voltage applied to the motor windings du -
ring activation of the DC-brake. The DC-brake is activate during the time when
terminal 30 is activated and after deactivation of terminal 30 for the time set by TAB1,
function t. Depending on TAB3, SUB XPAR, function SW1 the motor may automat-
ically restart at the end of DC-brake.
If a long DC-brake time is programmed, excessive motor
heating may result.
Range: 0...50%
Default: 15%
Function t: DC brake time
TAB1
After deactivating terminal 30 the DC-brake will remain active for the period set by this
parameter.
The motor may restart automatically at the end of the DC-brake
time depending on TAB3, SUB XPAR, function SW1.
Range: 0...20 sec.
Default: 0 sec.
Function E: Acceleration time ramp 2
TAB1
This parameter sets the time to accelerate the motor from 0 to 50 Hz.
Use the following formula to determine the proper time for other frequencies:
