The voltage supply of the holding brake has to be designed so as to guaran‐
tee under the worst installation and operation conditions that a sufficient volt‐
age 24 V ±10% is available at the motor in order to release the holding brake.
The voltage drop ΔU on the brake supply can approximately be calculated for
copper conductors using the following formula:
ΔU Voltage drop [V]
ρ
Cu
Specific resistance of copper [Ω*mm
2
/m]
l Cable length [m]
q
Wire cross section [mm 2 ]
I
N
Rated current [A]

the rated voltage (switching voltage)
CAUTION
For safe switching of the holding brake, a rated voltage of 24 V DC ±10% is
required at the motor.
Ensure correct dimensioning of the supply wires (wire length and cross-sec‐
tion) for the holding brake.
The control voltage can be reduced using the energy saving function after
safely releasing the brake, see chapter "Energy saving function for holding
brakes" on page 18 .
Protective circuit The holding brake in the motor is intended for direct connection to ctrlX and
IndraDrive controller.
The protective circuit to switch inductive loads of holding brakes is not inte‐
grated in MS2E motors. It is integrated in ctrlX and IndraDrive controllers of
Bosch Rexroth drive systems.
