Modbus Process Data<br />
Process data is processed in the M-Max frequency inverter faster than the display values,<br />
error codes and parameters.<br />
Input Process Data<br />
The input process data is used to control the M-Max frequency inverter.<br />
Control Word (ID 2001)<br />
These bits are used to control the M-Max frequency inverter. The content can be adapted to<br />
your own application and then sent as a control word to the frequency inverter.<br />

Description<br />
Bit<br />
Value = 0 Value = 1<br />
0 Stop Operation<br />
1 Clockwise rotating field (FWD) Anticlockwise rotating field (REV)<br />
2 No action Reset error<br />
3 As per setting P6.8 Free coasting (overwrite value from P6.8)<br />
4 As per setting P6.8 Ramp (overwrite value from P6.8)<br />
5 No action Overwrite acceleration/deceleration ramps to 0.1 s<br />
6 No action Block setpoint (speed not variable)<br />
7 No action Overwrite setpoint with 0<br />
8 No action Control level = Fieldbus (overwrite value from P6.8)<br />
9 No action Setpoint input = Fieldbus (overwrite value from P6.8)<br />
10 Not used —<br />
11 Not used —<br />
12 No action The inverter is blocked and the drive stops as quickly as possible<br />
(an edge is required for restart)<br />
13 No action Control of a digital output:<br />
P5.1 = 28 (Relay R01)<br />
P5.2 = 28 (Relay R02)<br />
P5.3 = 28 (Transistor D0)<br />
