6.5. Process Data PDI
6.5.1. PDI Word 1: Drive Control Word
The drive control word can be used to control the drive as follows:

6.5.2. PDI Word 2: Drive Speed Reference
The drive speed reference value has one decimal place, e.g. commanded value = 500, the drive setpoint frequency will be 50.0Hz.
6.5.3. PDI Words 3 and 4
As described in section 6.4.1. Process Data Exchange Overview, process data words 3 and 4 may be fixed function or configurable
function depending on the drive in use. The possible functions are described below.
6.5.4. Drive Torque Reference
Where supported by the drive and correctly configured in the drive parameters, the torque limit or reference may also be sent to
the drive using the fieldbus PDI. In this case, the value is sent with 1 decimal place, e.g. commanded value = 500, the drive torque
setpoint will be 50.0%.
6.5.5. Drive Ramp Times
When the drive parameters are configured to allow control of the drive ramp times through fieldbus, this register specifies the drive
acceleration and deceleration ramp times.
For P2 and Eco drives, when Fieldbus Ramp Control is selected (P5-08 = 1).
For E3 drives, setting P-12 = 4.
The input data range is from 0 to 60000 (0.00s to 600.00s for P2, 0.0 – 6000.0s for Eco).
6.5.6. User Registers
For P2 and Eco drives, which have internal function block programming capability, data may be written to the User Registers. This
allows control functions to be achieved within the drive by linking to the Group 9 parameters. The values may also be used within the
function block program.
6.6. Process Data PDO
PDO data is returned from the drive to the master PLC. The available data for each word is described below.
6.6.1. PDO Word 1: Drive Status Word
The function of PDO Word 1 is fixed for all drive models, and returns the drive Status Word. The individual bits within the drive status
word indicates the status of the drive as follows. Some functions are applicable to specific drive types, as indicated below.
