Bb1 = supply module ready (drive system)
Bb = drive module ready
K1 = mains contactor in supply module
K4 =holding brake control 1)
Q1 = power supply fuse
Q10 = main switch
RF = drive enable signal of the control unit
S1 = E-stop
S4 = power off
S5 = power on
Y1 = holding brake for feed axis with electrical release;
note the release delay! Speed command value
100 ms after RF on
Y2 = safety door locks
1) Only with holding brakes for feed drives that are not controlled by the drive module.
