User Relay 2 Output (Terminals 17 & 18) Function select
0

0
-
Selects the function assigned to Relay Output 2. The relay has two output terminals, Logic 1 indicates the relay is active, and therefore
terminals 17 and 18 will be linked together.
0 : Drive Enabled (Running).
Logic 1 when the motor is enabled.
1: Drive Healthy.
Logic 1 when power is applied to the drive and no fault exists.
2 : At Target Frequency (Speed).
Logic 1 when the output frequency matches the setpoint frequency.
3: Output Frequency > 0.0 Hz.
Logic 1 when the drive output frequency to the motor is exceeds 0.0Hz.
4 : Output Frequency >= Limit.
Logic 1 when the motor speed exceeds the adjustable limit.
5 : Output Current >= Limit.
Logic 1 when the motor current exceeds the adjustable limit.
6 : Output Torque >= Limit.
Logic 1 when the motor torque exceeds the adjustable limit.
7 : Analog Input 2 Signal Level >= Limit.
1 Logic when the signal applied to the Analog Input 2 exceeds the adjustable limit
8 : Assist Pump 1 DOL control.
This feature is not relevant if the drive is supplied by DC from a PV array.
Note:
When using settings 4 – 7, parameters P2-19 and P2-20 must be used together to control the behaviour. The output will switch
to Logic 1 when the selected signal exceeds the value programmed in P2-19, and return to Logic 0 when the signal falls below the
value programmed in P2-20.
9 : Reserved.
No Function.
10 : Maintenance Due.
Logic 1 when the internally programmable maintenance timer has elapsed.
11 : Drive Ready.
Logic 1 when drive is not tripped, STO circuit is closed, mains supply present, hardware enable input present.
12 : Drive Tripped.
Logic one when the drive has tripped and the display shows the fault code.
13 : STO Status.
Logic 1 when both STO inputs are present and the drive is able to be operated.
14 : PID Error >= Limit.
The PID Error (difference between setpoint and feedback) is greater than or equal to the programmed limit.
15 : High Load Detection Alarm.
Logic 1 when the load monitoring has been enabled using P8-06 to P8-08 and a high load
condition has been detected – usually used to signal pump blockage.

P2-21 & P2-22 allow the user to program the Optidrive to display an alternative output unit scaled from an existing parameter, e.g. to
display conveyer speed in metres per second based on the output frequency. This function is disabled if P2-21 is set to 0.
If P2-21 is set >0, the variable selected in P2-22 is multiplied by the factor entered in P2-21, and displayed whilst the drive is running,
with a ‘c’ to indicate the customer scaled units.
P2-22 Options
0: Motor Speed
1: Motor Current
2: Analog Input 2
3: P0-80 Value
4: Analog Input 1
Note:
P2-21 & P2-22 allow the user to program the Optidrive display to show an alternative output unit scaled from an existing
parameter (for example, to display conveyer speed in metres per second based on the output frequency).
This function is disabled if P2-21 is set to 0. If P2-21 is set >0, the variable selected in P2-22 is multiplied by the factor entered in P2-21,
and is shown on the drive display whilst the drive is running.
P2-23
Zero Speed Holding Time
0.0
60.0
0.2
Seconds
Determines the time for which the drive output frequency is held at zero when stopping, before the drive output is disabled.
P2-24
Effective Switching Frequency
Drive Rating Dependent
kHz
Effective power stage switching frequency. Higher frequencies reduce audible noise from the motor, and improve the output current
waveform, at the expense of increased drive losses.
Note:
De-rating of the drive output current may be required when increasing P2-24 beyond the minimum setting. Refer to section
11.3.3. Derating for Swicthing Frequency on page 67
for further information.
P2-25
Fast Decel Ramp Time
0.00
240.0
0.10
Seconds
This parameter allows an alternative deceleration ramp down time to be programmed into the Optidrive, which can be selected by
digital inputs (dependent on the setting of P1-13) or selected automatically in the case of a mains power loss if P2-38 = 2.
When set to 0.0, the drive will coast to stop.
