Description
See selection DI1(INV).
See selection DI1(INV).
Defines the maximum supplied current during torque boost. See parameter
2101 START FUNCTION.
Value in percent
applications where a smooth and quick restarting is essential. During the
delay the drive knows accurately the rotor position.
No Zero speed delay
Speed
Modulator switched
off: Motor coasts to
stop.
Zero speed
Zero speed delay can be used, for example, with jogging function (parameter
1010 JOGGING SEL).
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
modulator 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
modulator live: The inverter modulates, motor is magnetized and the drive is
ready for a quick restart.
Delay time. If parameter value is set to zero, the Zero speed delay function is
disabled.
Acceleration and deceleration times
Defines the source from which the drive reads the signal that selects
between two ramp pairs, acceleration/deceleration pair 1 and 2.
Ramp pair 1 is defined by parameters
DECELER TIME 1 and 2204
Ramp pair 2 is defined by parameters
DECELER TIME 2 and 2207
Ramp pair 1 is used.
Digital input DI1. 1 = ramp pair 2, 0 = ramp pair 1.

Inverted digital input DI1. 0 = ramp pair 2, 1 = ramp pair 1.
See selection DI1(INV).
With Zero speed delay
Speed
Modulator remains live. Motor
is decelerated to true 0
speed.
