Communication example
The following information is transmitted to the inverter when:
- The digital inputs have been configured and wired properly to enable the inverter.
Description | Value | Description | |
|---|---|---|---|
PA1 | Control word | 0x0000 | Stop along the second deceleration ramp (P2-25). |
0x0001 | Coast to a stop | ||
0x0002 | Stop along the process ramp (P1-04) or (PO3). | ||
0X0003 - 0x0005 | Reserved | ||
0x0006 | Accelerate along a ramp (P1-03) or (PO3) and run at setpoint speed (PO2). | ||
PA2 | Setpoint speed | 0x4000 | = 16384 dec. = maximum speed, e.g. 50 Hz (P1-01) CW |
0x2000 | = 8192 dec. = 50% of the maximum speed, e.g. 25 Hz CW | ||
0x0000 | = 0 dec. = minimum speed, set in P1-02 | ||
0xE000Display in pair's complement | = -8192 dec. = 50% of the maximum speed, e.g. 25 Hz CCW | ||
0xC000Display in pair's complement | = -16384 dec. = maximum speed, e.g. 50 Hz (P1-01) CCW | ||
The process data transmitted by the inverter should look as follows during operation:
Description | Value | Description | |
|---|---|---|---|
PE1 | Status word | 0x05C7 | Status = running, output stage enabled; inverter ready, PO data enabled |
PE2 | Actual speed | Should correspond to PO2 (setpoint speed)
| |
PE3 | Actual current | Dependent on rotational speed and load
| |
