DBT Reach Drive User Manual

Drive OL
Level 1

8

The calculated IGBT temperature requires a reduction in PWM
carrier frequency. If Drive OL Mode (150) is disabled and the load is
not reduced, an overload fault will eventually occur.

Drive OL
Level 2

9

The calculated IGBT temperature requires a reduction in Current
Limit. If Drive OL Mode (150) is disabled and the load is not
reduced, an overload fault will eventually occur.

Flux
Amps Ref
Rang

26

The calculated or measured Flux Amps value is not within the
expected range. Verify motor data and rerun motor tests.

Ground
Warn

15

Ground current has exceeded the level set in Gnd Warn Level (177).

Home
Not Set

34

Configurable alarm set in parameter 259, bit 17. When set to “1”,
this alarm is displayed when any of the following occur:

parameter 88 is set to “7” (Pos/Spd Prof)

on power up and parameter 88 = “7”

recall user sets and parameter 88 = “7”

Alarm is cleared when:

setting parameter 88 to a value other than “7”

reset defaults

parameter 259, bit 17 is cleared

a digital input is configured as “Set Home” and input is True

parameter 705, bit 9 is “Enabled”

parameter 700, bit 13 (At Home) is “Enabled” - position regulator
will set this bit if device is “home”

ln Phase
Loss

13

The DC bus ripple has exceeded the level set in Phase Loss Level
(545).

IntDBRes
OvrHeat

6

The drive has temporarily disabled the dynamic braking regulator
because the resistor temperature has exceeded a predetermined
value.

IR Volts
Range

25

The drive autotuning default is Calculate and the value calculated
for IR Drop Volts is not in the range of acceptable values. This alarm
should clear when all motor nameplate data is properly entered.

Ixo Vlt
Rang

28

Motor leakage inductance is out of range.

Load
Loss

14

Output torque current is below Load Loss Level (187) for a time
period greater than Load Loss Time (188).

MaxFreq
Conflict

23

The sum of Maximum Speed (82) and Overspeed Limit (83)
exceeds Maximum Freq (55). Raise Maximum Freq (55) or lower
Maximum Speed (82) and/or Overspeed Limit (83) so that the sum
is less than or equal to Maximum Freq (55).

Motor
Thermistor

12

The value at the thermistor terminals have been exceeded.
