The message is output if as response to a warning signal the quick-stop
79
function becomes active.
Error: can occur in the case of switched on brake control, if
the load is below the minimum load level at start up or the absence of an
56
engine phase was detected
the load is too high and the hardware current limit is reached
Adjusted monitoring time (Watchdog) of communication between opera-
18
tor and PC / operator and inverter has been exceeded.
60 Error: During the automatic motor stator resistance measurement.
54 Counter overflow encoder channel 1.
55 Counter overflow encoder channel 2.
Error: Overtemperature of motor PTC at terminals T1/T2. Error can only
be reset at E.ndOH, if PTC is again low-resistance. Causes:
resistance at the terminals T1/T2 >1650 Ohm
9
motor overloaded
line breakage to the temperature sensor
Error: Driver relay. Relay for driver voltage on power circuit has not pi-
51
cked up even though control release was given.
After reset the operation is again possible (without storage in the EE-
21
PROM)
Set speed and actual speed are different (see LF.46, LF.47, LF.48 and
31
LF.51)
32 Cable breakage on resolver or incremental encoder
52 Invalid encoder interface identifier.
Error: Encoder interface identifier has changed, it must be confirmed
59
over ec.00/ LC.11 or ec.10/ LC.21.
Hardware error at the NPN-/PNP changeover or the start/stop measure-
53
ment.
57 MFC not booted.
Load-shunt relay has not picked up. Occurs for a short time during the
switch-on phase, but must automatically be reset immediately. If the er-
ror message remains the following causes may be applicable:
load-shunt defective
15
input voltage wrong or too low
high losses in the supply cable
braking resistor wrongly connected or damaged
braking module defective
Motor temperature switch or PTC at the terminals T1/T2 is again in the
11
normal operating range. The error can then be reset.
Temperature of the heat sink is again in the permissible operating range.
36
The error can be reset now.
No longer overheating in the interior E.OHI, interior temperature has
7
fallen by at least 3°C, error can be reset.
