Error and Warning Messages
Introduction
The M-Max Series adjustable frequency drive have several internal monitoring functions.
When deviations from the optimal operating status are detected, faults (FAULT) and warning
messages (ALARM) are differentiated between.
Error messages
Faults can cause faulty functionality and technical defects. The inverter (adjustable frequency
drive output) is automatically disabled if a fault is detected. The connected motor then runs
down freely to a stop.
Error messages are shown on the display with an arrowhead under FAULT and with the
error code F… (F1 = last fault, F2 = last but one fault, etc.).
Figure 7: Error Message Example
Acknowledge fault message (Reset)
The current fault message flashes (for example, F1 09). It can be acknowledged with the
BACK/RESET key or by actuating DI5 (by default control signal terminal 15). The display
automatically changes from the flashing indication through four horizontal lines (Reset) to
the continuous display of the fault message. The arrow tip under FAULT goes out.
DANGER
When a start signal is applied, the drive restarts automatically if
P3.1 = 0 is set (REAF = restart after fault) and when the fault
message has been acknowledged (Reset).
The current fault message indication (F1...) is cleared when the power supply is interrupted
or when you press the BACK/RESET key and then the OK key (indication d...) and then the
BACK/RESET key again. The indication goes out and the arrow tip flashes at menu
level MON.
