IPOS SW limit
switch No
Response
In IPOS operating mode only:
Programmed target position is outside travel
range delimited by software limit switches.
• Check the user program
• Check position of software limit switches
81 Start condition
Immediate
disconnec-
tion
Only in "VFC hoist" operating mode:
The motor could not be supplied with the
correct amount of current during the
pre-magnetizing time:
•
Rated motor power too small in relation to
rated inverter power.
• Motor cable cross section too small.
• Check startup data and perform new
startup, if necessary.
• Check connection between inverter and
motor
• Check cross section of motor cable and
increase if necessary
82 Open output
Immediate
disconnec-
tion
Only in "VFC hoist" operating mode:
•
Two or all output phases interrupted.
• Rated motor power too small in relation to
rated inverter power.
• Check connection between inverter and
motor
• Check startup data and perform new
startup, if necessary.
84
Motor
protection Emergency
stop
•
Motor utilization too high.
• Reduce load
• Extend ramps
• Observe longer pause times
85 Copy
Immediate
disconnec-
tion
Error while copying parameters. Check connection between inverter and PC
87
Technology
function
Immediate
disconnec-
tion Attempt made to load the parameter set for an
application version unit with the technology
function activated into a standard version unit.
Activate the factory settings (P802 = YES) and
reset the unit
88 Flying start
Immediate
disconnec-
tion Only in VFC n-CTRL operating mode:
Actual speed > 5000 1/min when inverter
enabled.
Inverter not enabled before actual speed is
≤
5000 1/min.
94
EEPROM
checksum
Immediate
disconnec-
tion
Inverter electronics disrupted, possibly due to
effect of EMC or a defect.
Send unit in for repair
99
IPOS ramp
calculation
error Immediate
disconnec-
tion
In IPOS operating mode only:
Positioning ramp is sinusoidal or square and
an attempt is made to change ramp times and
traveling velocities with enabled inverter.
Rewrite the IPOS
plus®
program so that ramp
times and traveling velocities can only be
altered when the inverter is inhibited.
