Optidrive Eco User Guide Revision 2.01
When set to 1, the drive immediately carries out a non-rotating auto-tune to measure the motor parameters for optimum
control and efficiency. Following completion of the auto-tune, the parameter automatically returns to 0.
Vector Speed Controller Proportional Gain
Sets the proportional gain value for the speed controller. Higher values provide better output frequency regulation and
response. Too high a value can cause instability or even over current trips. For applications requiring best possible performance,
the value should be adjusted to suit the connected load by gradually increasing the value and monitoring the actual output
speed of the load until the required dynamic behaviour is achieved with little or no overshoot where the output speed exceeds
the setpoint.
In general, the factory set value will be suitable for most fan and pump applications, higher friction loads can tolerate higher
values of proportional gain, and high inertia, low friction loads may require the gain to be reduced.
Vector Speed Controller Integral Time Constant
Sets the integral time for the speed controller. Smaller values provide a faster response in reaction to motor load changes, at the
risk of introducing instability. For best dynamic performance, the value should be adjusted to suit the connected load.
When operating in Vector Speed motor control mode, this parameter must be set to the motor nameplate power factor
Maximum Motoring Current / Torque Limit
This parameter defines the maximum current or torque limit used by the drive.
Thermal Overload Value Retention
1 : Enabled. All Optidrives feature electronic thermal overload protection for the connected motor, designed to protect the
motor against damage. An internal overload accumulator monitors the motor output current over time, and will trip the drive if
the usage exceeds the thermal limit. When P4-12 is disabled, removing the power supply from the drive and re-applying will
reset the value of the accumulator. When P4-12 is enabled, the value is retained during power off.
1 : U, W, V. Direction of motor rotation when operating in a forward direction will be reversed.
10.4. Parameter Group 5 – Communication Parameters
Drive Fieldbus Address / MAC ID
Sets the Fieldbus address for the Optidrive.
When using Modbus RTU, this parameter sets the Node Address. Refer to section 11.2 for further information.
When Using BACnet MS/TP, this parameter sets the MAC ID. Refer to section 11.3 for further information.
Modbus RTU / BACnet Baud rate
Sets the baud rate when Modbus/BACnet communications are used
9.6kbps, 19.2kpbs, 38.4kpbs, 57.6kpbs, 115 kbps, 76.8kbps
Modbus RTU / BACnet Data Format
Sets the expected Modbus or BACnet 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
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 (P5-07)
Communications Loss Action
Controls the behaviour of the drive following a loss of communications as determined by the above parameter setting (P5-06).
0: Trip & Coast To Stop
1: Ramp to Stop Then Trip
2: Ramp to Stop Only (No Trip)
3: Run at Preset Speed 4
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
When using an optional Fieldbus interface, this parameter configures the parameter source for the 4th process data word
transferred from the drive to the network master during cyclic communications:
0 : Output Torque – Output power in kW to one decimal place, e.g. 500 = 50.0%
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 Heat-sink Temperature – 0 to 100 = 0 to 100°C
5 : User Register 1 – Can be accessed by PLC program or group 9 parameters
4 : User Register 2 – Can be accessed by PLC program or group 9 parameters
7 : P0-80 Value - P0-80 value can be selected by P6-28
