Energy saving function for holding brakes
Decrease brake voltage
The control voltage of 24 V DC ± 10% of the holding brake in MS2E holding
brakes can be reduced after executing the switching operation "Open brake"
by using control modules (e.g. IndraDrive brake control module
HAT02.1-003). By decreasing the control voltage, energy can be saved of up
to 50% and the self-heating of the motor can be reduced.
To decrease the control voltage of MS2E holding brakes, the following condi‐
tions apply:
●
Maximum decrease of control voltage to U
N
≥17 V DC am Motor
●
Waiting time after releasing the holding brake is at least 200 ms
●
Decreasing the control voltage by voltage control or pulse width modula‐
tion with a PWM cycle frequency ≥ 4 kHz
●
Ensure the functionality of the holding brake.
Refer to the instructions in the control module documentation.
Refer to the notes for dimensioning of the cable length and cable
cross-section of brake cables.
Safety and personal protection
The permanent magnet brake of MS2E motors is no safety brake. This
means, a torque reduction by non-influenceable disturbance factors can oc‐
cur. Especially for use in vertical axes.
