Optidrive ODE-3 1Ph Output User Guide Revision 1.00
Defines the access code which must be entered in P-14 to access parameters above P-14
0 : Unlocked. All parameters can be accessed and changed
1 : Locked. Parameter values can be displayed, but cannot be changed except P-38.
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 1 : Display Scaling Factor
Index 2 : Display Scaling Source
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%
PI Controller Proportional Gain
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
PI Controller Integral Time
PI Controller Integral Time. Larger values provide a more damped response for systems where the overall process responds slowly
PI Controller Operating Mode
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.
PI Reference (Setpoint) Source Select
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.
When P-44 = 0, this parameter sets the preset digital reference (setpoint) used for the PI Controller as a % of the feedback signal
range.
PI Feedback Source Select
Selects the source of the feedback signal to be used by the PI controller.
0 : Analog Input 2 (Terminal 4) Signal level readable in P00-02.
1 : Analog Input 1 (Terminal 6) Signal level readable in P00-01
2 : Motor Current. Scaled as % of P-08.
3 : DC Bus Voltage Scaled 0 – 1000 Volts = 0 – 100%
4 : Analog 1 – Analog 2. The value of Analog Input 2 is subtracted from Analog 1 to give a differential signal. The value is limited to 0.
5 : Largest (Analog 1, Analog 2). The larger of the two analog input values is always used for PI feedback.
Analog Input 2 Signal Format
= 0 to 10 Volt Signal
= 0 to 20mA Signal
= 4 to 20mA Signal, the Optidrive will trip and show the fault code if the signal level falls below 3mA
= 4 to 20mA Signal, the Optidrive will run at Preset Speed 1 (P-20) if the signal level falls below 3mA
= 20 to 4mA Signal, the Optidrive will trip and show the fault code if the signal level falls below 3mA
= 20 to 4mA Signal, the Optidrive will run at Preset Speed 1 (P-20) if the signal level falls below 3mA
= Use for motor thermistor measurement, valid with any setting of P-15 that has Input 3 as E-Trip. Trip level : 3kΩ, reset 1kΩ
When standby mode is enabled by setting P-48 > 0.0, the drive will enter standby following a period of operating at minimum speed
(P-02) for the time set in P-48. When in Standby Mode, the drive display shows , and the output to the motor is disabled.
PI Control Wake Up Error Level
When the drive is operating in PI Control Mode (P-12 = 5 or 6), and Standby Mode is enabled (P-48 > 0.0), P-49 can be used to define
the PI Error Level (E.g. difference between the setpoint and feedback) required before the drive restarts after entering Standby
Mode. This allows the drive to ignore small feedback errors and remain in Standby mode until the feedback drops sufficiently.
User Output Relay Hysteresis
Sets the hysteresis level for P-19 to prevent the output relay chattering when close to the threshold.
Thermal Overload Retention
0 : Disabled
1 : Enabled. When enabled, the drive calculated motor overload protection information is retained after the mains power is
removed from the drive.
