Error cause
M S
505
MB/ENC fault
Error:
Frequency inverter does not receive a rotary encoder signal at a target
speed >10 cm/s
Additional information:
Motor current in ampere
Remedy:
check motor connections (U
R
U; V
R
V; W
R
W),
Brake not closed during start,
Check the motor data
Check rotary encoder connection,
Increase/reduce the "SPD_KP" parameter in the "Control" menu

506
X_ENC15:Discon.
Error:
Rotary encoder signal interruption during travel
Remedy:
Check rotary encoder connection,
Switch frequency inverter off and then back on
515
v > 110% V*
Error:
Actual speed is
≥
110% of the nominal speed V*
Remedy:
Check whether the car counterweight is pulling up,
Check motor data in the "Motor name plate" menu,
Check the rotary encoder resolution in the "Encoder & BC" menu,
Check the "SPD_KP" parameter in the "Control system" menu,
●

516
v > 150% V*
Error:
Actual speed is
≥
150% of the nominal speed V*
Remedy:
Check whether the car counterweight is pulling up,
Check motor data in the "Motor name plate" menu,
Check the rotary encoder resolution in the "Encoder & BC" menu,
Check the "SPD_KP" parameter in the "Control system" menu,
●

519
Speed too low
Error:
The actual speed deviates from the target speed by -15%
Remedy:
Check rotary encoder connection,
Check the rotary encoder impulses in the "Info" menu, page 11,
Check the brake lifting
Check motor data in the "Motor name plate" menu,
Check the rotary encoder resolution in the "Encoder & BC" menu,
Increase "SPD_KP" ampli
fi
cation in the "Controller" menu

520
Wrong direction
Error:
Machine moves more than 12 cm in the wrong direction
Remedy:
Check rotary encoder connection,
Check the rotary encoder con
fi
guration in the "Encoder & BC" menu,
check the motor connections (U
R
U; V
R
V; W
R
W)
Frequency inverter design too small

522
ENC: Dif. Pos
Error:
Excessive positive difference between the rotary encoder counter sta-
tuses of two sampling steps. The limit value corresponds to double the nominal
system speed
Remedy:
Check whether the car counterweight is pulling up,
Check motor data in the "Motor name plate" menu,
Check the rotary encoder resolution in the "Encoder & BC" menu,
Check the "SPD_KP" parameter in the "Control system" menu,
Check the motor connection
●
●
523
ENC: Dif. neg
Error:
Excessive negative difference between the rotary encoder counter
statuses of two sampling steps. The limit value corresponds to double the
nominal system speed
Remedy:
Check whether the car counterweight is pulling up,
Check motor data in the "Motor name plate" menu,
Check the rotary encoder resolution in the "Encoder & BC" menu,
Check the "SPD_KP" parameter in the "Control system" menu,
Check the motor connection
●

525
ENC: 1387 ADC Limit
Fault:
signal track A or B of the absolute value or sinus encoder exceeding
permitted limit value during travel
Fault entry not made until end of travel
Travel not cancelled
Remedy:
Check sinus encoder,
Check the optional board for rotary encoder connection,
Check the rotary encoder type in the "Encoder & BC" menu,
