Control And State Bits; 6042H Object- Vl Target Velocity; 6043H Object- Vl Velocity Demand; 6044H Object- Vl Control Effort - WEG CFW-11 Communications Manual

6.2.1 Control and State Bits

The bits 4, 5, 6 and 8 of the control word (6040h object – Control word) have the following functions in the velocity
mode:
In order that the motor runs according to the acceleration ramp, it is necessary that the bit 4 be activated.
For the Statusword, the bits specified in the operation mode (bits 12 and 13) are reserved for future use.
6.2.2 6042h Object–
It allows programming the speed reference for the inverter, in rpm:
vl target velocity
The object
reverse speed direction. This change in the speed direction is performed through the writing of the bit 2 in the CAN
control word - P0684.
6.2.3 6043h Object–
It indicates the value of the speed reference after the ramp, in rpm:
6.2.4 6044h Object–
It indicates the speed value according to the measured at the motor, in rpm. For the control modes without
feedback, this object has the same value as the object 6043h.
