Par Name Minimum Maximum Default Units
P5-13 PDI-4 function select 0 1 0 -
0 Fieldbus ramps This option must be selected if the drive acceleration and
deceleration ramps are to be controlled from the eldbus. P5-07
must also be set to 1 to enable this function.
1 User register 4 The value received by the drive in PDI 4 is transferred to User Register
4. This option allows the function of the process data word to be
dened in Parameter Group 9. In this case, User Register 4 should not
be written to within any PLC function code, although the value can be
read.
P5-14 PDI-3 function select 0 2 0 -
0 Torque reference / limit This option must be selected if the drive output torque limit /
setpoint is to be controlled from the eldbus. This also requires
setting P4-06 = 3.
1 PID reference This option allows the setpoint to the PID controller to be received
from the Fieldbus. In order for this option to be used, P9-38 must be
set to 1, and the PID User setpoint must not be utilised within the PLC
function.
2 User register 3 The value received by the drive in PDI 3 is transferred to User Register
3. This option allows the function of the process data word to be
dened in Parameter Group 9. In this case, User Register 3 should not
be written to within any PLC function code, although the value can be
read.
P5-15 Modbus response delay 0 16 0 Chr
Allows the user to congure an additional delay between the drive receiving a request via the Modbus RTU
interface, and transmitting a reply. The value entered represents the delay in addition to the minimum
delay permissible according to the Modbus RTU specication, and is expressed as the number of additional
characters.
P5-16 Modbus drive address 0 273 0 -
The drive Modbus (and communication) address is set in P5-01 which has a maximum value of 63. If a higher
Modbus address is required for a larger network, it can be set in this parameter.
If this parameter is set to a value greater than 0, this address will become the Drive Modbus address. If this
value is set to 0, P5-01 determines the Drive Modbus address.
