t on drive output current (Refer to Pr 4.16)
20
Ensure the load is not jammed / sticking
Check the load on the motor has not changed
O.ht1
Drive overheat (thyristor junction) based on thermal model
21
Reduce ambient temperature
Reduce overload cycle
O.ht2
Heatsink over temperature
22
Check enclosure / drive fans are still functioning correctly
Check enclosure ventilation paths
Check enclosure door filters
Increase ventilation
Decrease acceleration / deceleration rates
Reduce duty cycle
Reduce motor load
O.ht3
External discharge resistor over temperature
27
The temperature of the external discharge resistor is monitored by the temperature accumulators. When the resistor temperature
(Pr
11.65
) reaches 100
%
the drive will trip
See Pr
11.62
, Pr
11.63
and Pr
11.64
O.Ld1
Digital output overload: total current drawn from 24V supply and digital outputs exceeds 200mA
26
Check total load on digital outputs (terminals 24,25,26)and +24V rail (terminal 22)
O.SPd
Motor speed has exceeded the over speed threshold
7
The drive will trip O.SPd if the armature is open circuit when the drive is in estimated speed mode.
Check armature circuit
If the speed feedback (Pr
3.02
(
di05, 0.40
)) exceeds the over speed threshold (Pr
3.08
) in either direction an over speed trip is
produced. If this parameter is set to zero, the over speed threshold is automatically set to 1.2 x Pr
1.06
(
SE02, 0.23
) or Pr
1.07
(
SE01, 0.22
).
Reduce the speed loop gain (Pr
3.10
(
SP01, 0.61
)) and speed integral (Pr
3.11
(
SP02, 0.62
)) to prevent speed overshoot.
