Figure 6.7 Re-leveling Travel without Electric Stop (DCP3)
If the drive controller enable is not switched off, the motor contactors will be carrying current when opened.
Since the motor is not being supplied with power during the time elapsing until the mechanical brake is applied,
the drive can coast. Therefore, the method described in the next section is of advantage.
Re-leveling Travel not Dependent on Remaining Distance with Electric Stop :
The following method allows smooth stopping:
1. Before the travel starts, the speed mode "Releveling [bit G1]" (VN) is transmitted.
2. The travel starts with activation of travel command bit B1, but the stop switch is not set.
3. After the travel command bit B1 has been switched off, drive controller enable bit B0 remains activated. The
drive decelerates to 0 and holds the car until the mechanical brake is applied.
4. Drive controller enable bit B0 and the motor contactors are not switched off until the mechanical brake bit S6
and travel activated bit S1 are switched off.
