Optidrive ODP-2 User Guide Revision 2.10
8.4. Parameter Group 5 – Communication Parameters
Sets the fieldbus address for the Optidrive
Sets the baud rate when CAN Open communications are used
Sets the baud rate when Modbus RTU communications are used
Sets the expected Modbus telegram data format as follows :-
: No Parity, 1 stop bit
: Odd parity, 1 stop bit
: No parity, 2 stop bits
: Even parity, 1 stop bit
Communications Loss Timeout
Sets the watchdog time period for the communications channel. 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.
Communications Loss Action
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
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
Fieldbus Process Data Output Word 4 Select
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 communications
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
Fieldbus Process Data Output Word 3 Select
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.
Fieldbus Process Data Input Word 4 Select
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 PLC
function code, although the value can be read.
Fieldbus Process Data Input Word 3 Select
When using an optional fieldbus interface, this parameter configures destination for the 3
rd
process data word received by the
drive from the network master during cyclic communications
0: Torque limit/reference – This option must be selected if the drive output torque limit / setpoint is to be controlled from the
fieldbus. This also requires setting P4-06 = 3.
1: User PID reference register – 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 defined 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.
Allows the user to configure 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 specification, and is expressed as the number of additional characters.
