Actual signals and parameters 203
2110 TORQ BOOST
CURR
Defines the maximum supplied current during torque boost.
See parameter 2101 START FUNCTION .
100%
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.
0.00 s
0.0…60.0 s Delay time 1 = 0.01 s
2114 HEATING
CURR REF [%]
Defines the amount of current to use for motor heating
relative to the nominal current of the motor.
0.0%
0.0…30.0 % Percent of heating current 1 = 0.1 %
2115 MOT. HEATING
SEL
Selects the source for controlling motor heating. OFF
OFF Motor heating inactive. Can also be used to switch off the
injection during heating.
