22.03
MOTOR GEAR MUL
(see above)
Defines the motor gear numerator for the motor encoder gear function.
where input speed is encoder 1/2 speed (
) or
speed estimate (
).
See section

Numerator for motor encoder gear.
Note:
A setting of 0 is changed
internally to 1.
22.04
MOTOR GEAR DIV
(see above)
Defines the motor gear denominator for the motor encoder gear function. See parameter
.

Denominator for motor encoder gear.
22.05
ZERO SPEED LIMIT
(see above)
Defines the zero speed limit. The motor is stopped along a speed ramp until the defined zero speed
limit is reached. After the limit, the motor coasts to stop.
Note:
Too low a setting may result in the drive not stopping at all.
0…30000 rpm
Zero speed limit.
22.06
ZERO SPEED DELAY
(see above)
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 function keeps the speed controller live: the inverter modulates, motor is magnetised and the drive
is ready for a quick restart. Zero speed delay can be used e.g. with the jogging function.
0…30000 ms
Zero speed delay.
