2110 TORQ BOOST 
CURR
Defines the maximum supplied current during torque boost.

15…300% Value in percent 1 = 1%
2112 ZERO SPEED 
DELAY
Defines the delay for the Zero speed delay function. The 
function is useful in applications where a smooth and quick 
restarting is essential. During the delay the drive knows 
accurately the rotor position.
No Zero speed delay
The drive receives a stop command and decelerates along 
a ramp. When the motor actual speed falls below an internal 
limit (called Zero speed), the speed controller is switched 
off. The inverter modulation is stopped and the motor coasts 
to standstill.
With Zero speed delay
The drive receives a stop command and decelerates along 
a ramp. When the actual motor speed falls below an internal 
limit (called Zero speed), the zero speed delay function 
activates. During the delay the functions keeps the speed 
controller live: The inverter modulates, motor is magnetized 
and the drive is ready for a quick restart.
0.0 s
0.0 = NOT SEL
0.0…60.0 s
Delay time. If parameter value is set to zero, Zero speed 
delay function is disabled.
1 = 0.1 s
2113 START DELAY Defines the start delay. 
After the conditions for start have been fulfilled, the drive 
waits until the delay has elapsed and then starts the motor. 
Start delay can be used with all start methods. Enabling 
start delay does not prevent modulation.
If start delay is zero, the delay is disabled. During the start 
delay, alarm START DELAY is shown.

2114 HEATING 
CURR REF [%]
Defines the amount of current to use for motor heating 
relative to the nominal current of the motor.

0.0…30.0 % Percent of heating current 1 =  0.1 %

SEL
Selects the source for controlling motor heating. OFF
OFF Motor heating inactive. Can also be used to switch off the 
injection during heating.
