Control word 1
Control word 1 includes the most important drive functions of the basic control block as well as the function bits for setpoint functions that are generated in the MOVITRAC® B frequency inverter in the higher-order byte.
Bit | Function | Assignment |
|---|---|---|
0 | Fixed definition | Controller inhibit "1" / enable "0" |
1 | Enable "1" / rapid stop "0" | |
2 | Enable "1" / stop "0" | |
3 | Reserved | |
4 | Integrator switchover | |
5 | Parameter set switchover | |
6 | Reset | |
7 | Reserved | |
8 | Direction of rotation for motor potentiometer | 0 = CW direction of rotation 1 = CCW direction of rotation |
9 10 | Motor potentiometer acceleration Motor potentiometer deceleration | 10 9 0 0 = no change 1 0 = down 0 1 = up 1 1 = no change |
11 12 | Selection of the internal fixed setpoints n11 - n13 or n21 - n23 | 12 11 0 0 = Speed setpoint via process output data word 2 0 1 = Internal setpoint n11 (n21) 1 0 = Internal setpoint n12 (n22) 1 1 = Internal setpoint n13 (n23) |
13 | Fixed setpoint switchover | 0 = Fixed setpoints of the active parameter set can be selected using bit 11/12 1 = Fixed setpoints of the other parameter set can be set using bit 11/12 |
14 | Reserved | Set reserved bits to zero. |
15 | Reserved | Set reserved bits to zero. |
These internal setpoint functions are activated by setting parameter P100 to fixed setpoint or motor potentiometer and setting the matching bits in control word 1. Any speed setpoint entered via an SBus process output data word will no longer be effective.
