Maximum current carrying capacity of outputs X6: 1.25 A
⇒ R = U / 1.25 A

R : Minimum allowed resistance of the motor holding brake
br (min)
U : Maximum supply voltage of the motor holding brake
br (max)
If U = 24 V +5% = 25.2 V, this results in:
br (max)
R = 20.16 Ω (applicable to all operating and ambient conditions)

Make sure the power supply for the motor holding brake at the motor is suffi‐
cient. You have to take into account that voltage drops on the supply line.
Use connection lines with the highest possible cross section of the single
strands.
Use an external contact element in accordance with the required safety cate‐
gory, if you wish to supply motor holding brakes with higher currents than the
allowed current load at X6. Make sure to comply with the required minimum
current consumption of 100 mA when using the external contact element.
Otherwise, the brake current monitoring unit signals an error.
