IMPDRVIncr and IMPDRVVelo signals
The signals IMPDRVIncr and IMPDRVVelo are in the low byte of TZW2 (bits 0 to 2, and bits 3 to 5). 
Both have a numeric structure.

Note
When the sequential control system changes to the state "S4: Z_Mode" (see Figure 5-4 
Sequential control state graph (Page 163)) the IMPDRVIncr and IMPDRVVelo signals as well as 
the lead time are reset. This decouples the ImpDrv signals from the service mode (local 
operation) and operating mode.
You will nd further information about the IMPDRVIncr and IMPDRVVelo signals and the 
corresponding drive function in section ImpulseDrive (Page 80).
