Value Meaning
68 It is stopped with the adjusted ramp times in anti-clockwise direction of
rotation.
121 The drive signals that it is ready to start the positioning process.
71 This message is displayed if during constant operation the load is
limited to the adjusted current limit.
81 Search for reference point approach active.
74 Speed search function active, that means that the inverter attempts to
synchronize onto a running down motor.
79 The message is output if as response to a warning signal the quick-
stop function becomes active.
56 Error: This error can occur in the case of switched on brake control
(see Chapter 6.9.5), if
• the load is below the minimum load level (Pn.43) at start up or the
absence of an engine phase was detected.
• the load is too high and the hardware current limit is reached
18 Error: Adjusted monitoring time (Watchdog) of communication
between operator 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
9 Error: Overtemperature of motor PTC. Error can only be reset at
E.ndOH, if PTC is again low-resistance. Causes:
• resistance at the terminals T1/T2 >1650 Ohm
• motor overloaded
• line breakage to the temperature sensor
51 Error: Driver relay. Relay for driver voltage on power circuit has not
picked up even though control release was given.
21 After reset the operation is again possible (without storage in the
EEPROM)
31 Error: External error. Is triggered, if a digital input is being
programmed as external error input and trips.
32 Cable breakage of encoder at encoder interface 1
Encoder temperature is too high
Speed is too high
Encoder signals are out of specification
Encoder has an internal error
34 Cable breakage of encoder at encoder interface 2
Encoder temperature is too high
Speed is too high
Encoder signals are out of specification
Encoder has an internal error
35 Operation of a synchronous motor with intelligent interface:
• Encoder is not connected during the start
• Encoder was changed
The error can be reset by writing on ec.0.
52 Invalid encoder interface identifier
