This parameter has three sub settings used to configure the Modbus RTU Serial Communications. The Sub Parameters are:
1st Index:
Drive Address:
Range: 0 – 63, default: 1.
2nd Index:
Baud Rate & Network type:
Selects the baud rate and network type for the internal RS485
communication port.
For Modbus RTU: Baud rates 9.6, 19.2, 38.4, 57.6, 115.2 kbps are available.
For CAN: Baud rates 125, 250, 500 & 1000 kbps are available.
3rd Index: Watchdog Timeout:
Defines the time for which the drive will operate without receiving a valid command telegram
to Register 1 (Drive Control Word) after the drive has been enabled. Setting 0 disables the Watchdog timer. Setting a value of 30,
100, 1000, or 3000 defines the time limit in milliseconds for operation. A ‘
’ suffix selects trip on loss of communication. An ‘
’ suffix
means that the drive will coast stop (output immediately disabled) but will not trip.
P-37
Access Code Definition

Defines the access code which must be entered in P-14 to access parameters above P-14.
P-38

0
-
0: Unlocked.
All parameters can be accessed and changed.
1: Locked.
Parameter values can be displayed, but cannot be changed except P-38.
P-39
Analog Input 1 Offset
-500.0
500.0
0.0
%
Sets an offset, as a percentage of the full scale range of the input, which is applied to the analog input signal. This parameter
operates in conjunction with P-35, and the resultant value can be displayed in P00-01.
The resultant value is defined as a percentage, according to the following:
P00-01 = (Applied Signal Level(%) - P-39) x P-35).

Index 2: Display Scaling Source
0
3
0
-
Allows the user to program the Optidrive to display an alternative output unit scaled from either output frequency (Hz), Motor
Speed (RPM) or the signal level of PI feedback when operating in PI Mode.
Index 1:
Used to set the scaling multiplier. The chosen source value is multiplied by this factor.
Index 2:
Defines the scaling source as follows:
0: Motor Speed.
Scaling is applied to the output frequency if P-10 = 0, or motor RPM if P-10 > 0.
1: Motor Current.
Scaling is applied to the motor current value (Amps).
2: Analog Input 2 Signal Level.
Scaling is applied to analog input 2 signal level, internally represented as 0 – 100.0%.
3: PI Feedback.
Scaling is applied to the PI feedback selected by P-46, internally represented as 0 – 100.0%.
P-41
PI Controller Proportional Gain
0.0
30.0
1.0
-
PI Controller Proportional Gain. Higher values provide a greater change in the drive output frequency in response to small changes
in the feedback signal. Too high a value can cause instability.
P-42
PI Controller Integral Time
0.0
30.0
1.0
5
PI Controller Integral Time. Larger values provide a more damped response for systems where the overall process responds slowly.
P-43
PI Controller Operating Mode
0
1
0
-
0: Direct Operation.
Use this mode if when the feedback signal drops, the motor speed should increase.
1: Inverse Operation.
Use this mode if when the feedback signal drops, the motor speed should decrease.
2: Direct Operation, Wake at Full Speed.
As setting 0, but on restart from Standby, PI Output is set to 100%.
3: Reverse Operation, Wake at Full Speed.
As setting 0, but on restart from Standby, PI Output is set to 100%.
P-44
PI Reference (Setpoint) Source Select
0
1
0
-
Selects the source for the PID Reference / Setpoint.
0: Digital Preset Setpoint.
P-45 is used.
1: Analog Input 1 Setpoint.
Analog input 1 signal level, readable in P00-01 is used for the setpoint.
P-45
PI Digital Setpoint
0.0
100.0
0.0
%
When P-44 = 0, this parameter sets the preset digital reference (setpoint) used for the PI Controller as a % of the feedback signal.
