1. Start motor and control system!
Danger!
The running rotor must not be touched.
Danger!
Live connections must not be touched.
2. Observe air gap "s
Lü
" during operation of the drive. The air gap must be zero.
3. Measure the DC voltage at the brake.
– The DC voltage measured after the overexcitation time (see bridge/half−wave
rectifier,
32) must correspond to the holding voltage (
34). A ±10 % deviation
is permissible.
