Description
Corrective Action
-
11
External trip
E-trip requested on control input terminals. Some settings of P1-13 require a normally closed
contact to provide an external means of tripping the drive in the event that an external device
develops a fault. If a motor thermistor is connected check if the motor is too hot.
S-
12
Communications Fault
Communications lost with PC or remote keypad. Check the cables and connections to external
devices.
-
13
Excessive DC ripple
The DC Bus Ripple Voltage level can be displayed in parameter P0-16.
A historical log is stored at 20ms intervals prior to a trip in parameter P0-37.
Check all three supply phases are present and within the 3% supply voltage level imbalance
tolerance.
Reduce the motor load.
If the fault persists, contact your local Invertek Drives Sales Partner.
P-
14
Input phase loss
Drive intended for use with a 3 phase supply, one input phase has been disconnected or lost.

Instantaneous over
current on drive output

Faulty thermistor on
heatsink
Refer to your Invertek Sales Partner.

17
Internal memory fault
Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your IDL Authorised Distributor.
-
18
4-20mA Signal Lost
The reference signal on Analog Input 1 or 2 (Terminals 6 or 10) has dropped below the minimum
threshold of 3mA. Check the signal source and wiring to the Optidrive terminals.
-
19
Internal memory fault
Parameters not saved, defaults reloaded.
Try again. If problem recurs, refer to your IDL Authorised Distributor.

User Parameter Default
User Parameter defaults have been loaded. Press the Stop key.

21
Motor PTC Over
Temperature
The connected motor PTC device has caused the drive to trip.
-
22
Cooling Fan Fault
Check and if necessary, replace the drive internal cooling fan.
-he
23
Ambient Temperature
High
The measured temperature around the drive is above the operating limit of the drive.
Ensure the drive internal cooling fan is operating.
Ensure that the required space around the drive as shown in sections
3.9. Guidelines for Mounting (IP66 Units)
has been observed, and that the cooling
airflow path to and from the drive is not restricted.
Increase the cooling airflow to the drive.
Reduce the effective switching frequency setting in parameter P2-24.
Reduce the load on the motor / drive.
-q
24
Maximum Torque Limit
Exceeded
The output torque limit has exceeded the drive capacity or trip threshold.
Reduce the motor load, or increase the acceleration time.
-q
25
Output Torque Too Low
Active only when hoist brake control is enabled P2-18 = 8. The torque developed prior to releasing
the motor holding brake is below the preset threshold. Contact your local Invertek Sales Partner for
further information on using the Optidrive P2 in hoist applications.

Drive output fault
Drive output fault.

Internal STO circuit Error Refer to your Invertek Sales Partner.

30
Encoder Feedback Fault Encoder communication /data loss.
SP-
31
Speed Error
Speed Error. The error between the measured encoder feedback speed or the estimated rotor
speed is greater than the pre-set limit allowed. In Hoist Mode Operation, this protection is always
active even if no encoder is fitted. The motor speed deviates from the intended motor speed by an
error greater than that set in the limit parameter P6-07.
-
32
Encoder Feedback Fault Incorrect Encoder PPR count set in parameter P6-06.
-
33
Encoder Feedback Fault Encoder Channel A Fault.
-
34
Encoder Feedback Fault Encoder Channel B Fault.
-
35
Encoder Feedback Fault Encoder Channels A & B Fault.
