F 51 Stop limit
Stop limit has tripped Reset: keep controller at zero >300ms.
Ensure that fault disappears after leaving the stop
limit.
Board Fault Reset: switch power off and restart after the lamps
of keypad are off.
Check:
F 56 Generator side
current limit Too short deceleration time Reset has an additional 5 s time delay.
Check:
F 57
Thermistor fault Thermistor input in relay / thermistor board has
detected motor overtemperature. Fault appears
when thermistor input has been open over 1s. Check:
F 60 Parameter fault Inverter has lost parameters. Drive selection
parameter has changed to 0 / none. Download parameters from keypad
F 61 Overspeed Fault SSU has tripped to Overspeed (hardware
supervision). Motor speed has increased above
overspeed detection level. Reset when 1s without pulses from pulse
sensor/encoder to SSU and controller at zero
position.
Check:
F 62 Speed Difference
Fault SSU has tripped to Speed Difference Reset when 1s without pulses from pulse
sensor/encoder to SSU and controller at zero
position.
F 63 Stall Supervision
Fault
SSU has tripped to Stall. Reset when 1s without pulses from pulse
sensor/encoder to SSU and controller at zero
position.
Check:
F 64 SSU Relay Test
Fault Relay in SSU board is damaged or SSU relay is
bypassed Reset: switch power off and restart after the lamps
of keypad are off.
Check:
F 65 SSU Watchdog SSU internal fault Reset: switch power off and restart after the lamps
of display are off.
Check:
F 66 SSU Overspeed
Limit SSU overspeed limit has been set over 140% of
maximum frequency Check:
F 70 Multicare Fault Other D2L has tripped to fault or brake of other D2L
has not been opened. Fault is not stored into fault
history. Check other hoisting inverter:
F 71 Brake Control Fault
Load information from hoist control unit is out of
operation window Check
F 55
- Some of following board is missing:
-
A = Basic I/O board
-
B = Thermistor board
-
D = Expansion board
- board slots A, B and D
- drive selection
- control mode
- generator side current limit
- deceleration time
-
motor cooling and loading
-
thermistor connection. If expansion board
thermistor input is not used, it should be
shorted
- motor parameters
- the brake operation
- function and cabling
- maximum frequency setting parameters
- SSU settings
Check:
-
pulse sensor/encoder function and cabling
-
pulse sensor/encoder pulse number
- speed difference supervision settings
- brake operation
- pulse sensor/encoder function and cabling
- stall supervision settings
- ES and RDY external connections
- OK input operation
- change SSU board
- interference fault between SSU board and
control board
-
component failure (control board or SSU
board)
- SSU status (System menu / System info /
Expander boards / C: SSU / status)
-
SSU LED’s
If the fault comes again, contact service
- set SSU overspeed limit under 140% of
maximum frequency
- motor type plate parameters
- maximum frequency parameters
-
fault history
- brake operation
- Ain2 wiring
- settings of load measuring device
