Error message: "Error! Output phase“ (E.iPH)
Pn.74 Out phase check mode
Value range: 0 (off) .. 1 (on), default value: 0 (off), not set-programmable
Function:
The function is active if all following conditions are met:
Pn.74 = 1 (on)
F5-G or F5-M vvc (cs.00 Bit 0-2 = 0..2)
Output frequency ru.03 > 4 Hz
Utilization ru.13 > Utilization lower limit
Since checking of the phase currents is done with a constant ADC level, the result of the utilization lower limit
is dependent on the value of the overload characteristic:
HRS / OC Utilization lower limit
125 / 150 % 4.8 %
150 / 180 % 5.7 %
180 / 216 % 6.9 %
200 / 240 % 7.6 %
The release time sets itself load and frequency-dependent between 250 and approx. 400 ms. The cause there-
fore is the strong uctuating load after disconnecting a phase. The load can fall temporary below the utilization
lower limit, whereby the release time is extended.
7.13.2 Response to malfunction messages
7.13.2.1 Selection of the response
Abnormal stopping (i.e., automatic shutdown of the drive) is possible for all errors that do not enforce immediate
shutdown of the modulation or for which pre-warnings can be generated.
If abnormal stopping is not sensible in the application, the possibility to set a digital output is available for many
malfunctions.
The response is programmable for the following malfunctions:
- Ext. error Pn.03 Reaction to external fault
- Watchdog Pn.05 Watchdog response
- Hardware limit switch Pn.07 proh. rot. stopping mode
- Set selection error Pn.18 E.Set stopping mode
- Software limit switch Pn.66 Response software limit switch
- Speed controller limit Pn.75 Response to error E.SCL
- Acceleration monitoring Pn.81 Acceleration error response
Other errors switch off the modulation, but a pre-warnings can be generated prior to their triggering. In the time
between the pre-warning signal and the triggering of the error, the drive can be hut down via abnormal stopping.
The response is programmable:
- overload Pn.08 warning OL stop. mode
- Heat sink overtemperature Pn.10 Heat sink overtemperature response
- internal overtemperature Pn.16 Internal overtemperature response
