1) Only for feed drive holding brakes which are not controlled by the drive module.
Bb1 = supply module ready (drive system)
Bb = drive ready contact of drive module
F1 = fuse for input power
F2 = electronics and blower fuses
K1 = mains contactor
K3 = decoupling Bb1
K4 = holding brake control
K10 = decouple thermal contact for power transformer
NC = error signal from the control
Q10 = mains disconnect
RF = drive enable signal from controller
S1 = E-Stop
S2 = axis limit switch
S4 = power OFF
S5 = power ON
T1 = power transformer
Y1 = Take delay time of electrically released holding brake
of feed axes into account! Do not apply velocity
command until 100 ms after RF-ON!
