-
Sets the expected Modbus telegram data format as follows
: No Parity, 1 stop bit
: No parity, 2 stop bits
: Odd parity, 1 stop bit
: Even parity, 1 stop bit
P5-05
Communications Loss Timeout
0.0
5.0
2.0
Seconds
Sets the watchdog time period for the communications channel for fieldbus systems where the drive must monitor for loss of
communications with the network master, e.g. Modbus RTU. If a valid telegram is not received by the Optidrive within this time
period, the drive will assume a loss of communications has occurred and react as selected below. Setting to zero disables the
function.
P5-06
Communications Loss Action
0
3
0
-
Controls the behaviour of the drive following a loss of communications as determined by the above parameter setting.
0 : Trip & Coast To Stop
1 : Ramp to Stop Then Trip
2 : Ramp to Stop Only (No Trip)
3 : Run at Preset Speed 8
P5-07
Fieldbus Ramp Control
0
1
0
-
Selects whether the acceleration and deceleration ramps are control directly via the Fieldbus, or by internal drive parameters P1-03
and P1-04.
0 : Disabled
. Ramps are control from internal drive parameters
1 : Enabled
. Ramps are controlled directly by the Fieldbus
P5-08
Fieldbus Process Data Output Word 4 Select
0

0
-
When using an optional fieldbus interface, this parameter configures the parameter source for the 4
th
process data word transferred
from the drive to the network master during cyclic communication.
0 : Output Torque
– 0 to 2000 = 0 to 200.0%
1 : Output Power
– Output power in kW to two decimal places, e.g. 400 = 4.00kW
2 : Digital Input Status
– Bit 0 indicates digital input 1 status, bit 1 indicates digital input 2 status etc.
3 : Analog Input 2 Signal Level
– 0 to 1000 = 0 to 100.0%
4 :
Drive Heatsink Temperature
– 0 to 100 = 0 to 100°C
5 : User Register 1
6 : User Register 2
7 : P0-80 Value

0
-
When using an optional fieldbus interface, this parameter configures the parameter source for the 3
rd
process data word transferred
from the drive to the network master during cyclic communications
0 : Motor current
– Output current to 1 decimal place, e.g. 100 = 10.0 Amps
1 : Power (x.xx kW)
Output power in kW to two decimal places, e.g. 400 = 4.00kW
2 : Digital input status
– Bit 0 indicates digital input 1 status, bit 1 indicates digital input 2 status etc.
3 : Analog Input 2 Signal Level
- 0 to 1000 = 0 to 100.0%
4 : Drive Heatsink Temperature
– 0 to 100 = 0 to 100°C
5 : User register 1
– User Defined Register 1 Value
6 : User register 2
– User Defined Register 1 Value
7 : P0-80 value
– User Selected data value – see section 0

Fieldbus Process Data Input Word 4 Select
0
1
0
-
When using an optional fieldbus interface, this parameter configures destination for the 4
th
process data word received by the drive
from the network master during cyclic communications
0 : Fieldbus Ramp Control
– This option must be selected if the drive acceleration and deceleration ramps are to be controlled from
the fieldbus. 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 defined in Parameter Group 9. In this case, User Register 4 should not be written to within any Function
Block code, although the value can be read. Refer to section 1.4 for further information.
