Value Meaning
69 The acceleration / deceleration phase is completed and it is
driven with constant speed / frequency in anti-clockwise
direction of rotation.
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
