Start and Stop the Drive

The following table shows the additional control bits which could be linked to OFF1 and OFF3 at the Function Block ACSM1_ACCESS_dc. These additional control bits could be set to “TRUE” to have full control through Fieldbus interface or could be mapped to binary inputs.

Parameter Name Value Mnemonic Function
START/STOP
10.10 EM STOP OFF3 1

True

Bit pointer

Default, controlled by Fieldbus.

The drive is stopped along the emergency stop ramp time, 25.11 EM STOP TIME.

10.11 EM STOP OFF1 1

True

Bit pointer

Default, controlled by Fieldbus.

Stop along the currently active deceleration ramp.

For example:

The drive will execute an OR-Connection from 10.10 and the OFF3-Bit at the ACSM1_ACCESS_dc Block to stop along the emergency ramp. With 10.10 = Bit pointer, the drive might be forced to stop along an emergency ramp without using the PLC to initialize this. This measure allows managing emergency situations without the PLC.
