Special function 9

MOVIMOT

®

for hoist applications

Pre-requisites

MOVIMOT

®

may only be used in hoist applications if the following pre-requisites

are met:

Special function 9 is only possible in connection with brake motors.

Ensure that VFC operation (DIP switches S2/3 = OFF) is selected.

The use of brake control BGM in connection with an external braking resistor is im-
perative (starting on page 75).

It is recommended to activate the function "Speed monitoring" (page 57) .

Function descrip-
tion

The start frequency is 2 Hz with terminal and bus operation. If the function is not ac-
tivated, the start frequency is 0.5 Hz.

The brake release time is fixed at 200 ms (standard = 0 ms), which prevents the mo-
tor from working against the applied brake.

The brake reaction time (post-magnetization time) is 150 ms (standard = 100 ms),
which ensures that the brake is applied as soon as the motor stops generating
torque.

The subsequent behavior of MOVIMOT

®

is dependent on the operating mode (see

page 70).
