22.03 MOTOR GEAR MUL FW block: SPEED FEEDBACK (see above)
Defines the motor gear numerator for the motor encoder gear function.
where input speed is encoder 1/2 speed (1.08 ENCODER 1 SPEED / 1.10 ENCODER 2 SPEED) or
speed estimate (1.14 SPEED ESTIMATED).
Note: If the motor gear ratio differs from 1, the motor model uses an estimated speed instead of the
speed feedback value.
See also section Motor encoder gear function on page 54.

-1 Numerator for motor encoder gear. Note: A setting of 0 is changed
internally to 1.
22.04 MOTOR GEAR DIV FW block: SPEED FEEDBACK (see above)
Defines the motor gear denominator for the motor encoder gear function. See parameter 22.03
MOTOR GEAR MUL.

-1 Denominator for motor encoder gear.
22.05 ZERO SPEED LIMIT FW block: SPEED FEEDBACK (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.
