External 24 VDC power supply
A 24 VDC power supply is needed to supply the V90 PN servo drive. Refer to the table
below to select the power supply:
Without a holding brake
Rated voltage (V)
24 (-15% to +20%)
The minimum voltage of 24 VDC -10% must be available at the connector on the motor side in
1)
order to guarantee that the brake reliably opens. If the maximum voltage of 24 VDC +10% is ex-
ceeded, then the brake could re-close. The voltage drop along the brake feeder cable must be
taken into consideration. The voltage drop ΔU for copper cables can be approximately calculated
as follows:
ΔU [V] = 0.042 Ω·mm
Where: l = Cable length [m], q = Brake cable cross section [mm
Fuse/Type-E combination motor controller
A fuse/type-E combination motor controller/circuit breaker can be used to protect the system.
Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electrical Code and any
additional local codes. Refer to the table below for the selection of fuses, type-E combination
motor controllers, and circuit breakers:
