10.8 Option error External module communication failure
• Connection fault / error in the external module
• Brief interruption (<1sec) of the 24 V supply of the
internal CAN/CANopen bus

E011 11.0 Customer interface Error in analog-digital converter
• Internal customer unit (internal data bus) faulty or
damaged by radio radiation (EMC)
• Check control terminals connection for short-circuit.
• Minimize EMC interference by laying control and
power cables separately.
• Earth the devices and shields well.

E012 12.0 External watchdog The Watchdog function is selected at a digital input and the
impulse at the corresponding digital input is not present for
longer than the time set in parameter P460 >Watchdog
time<.
• Check connections
• Check P460 setting
12.1 Motor limit
"Motor switch-off limit"
The motor switch-off limit P534 [-01] has triggered.
• Reduce load on motor
• Set higher value in (P534 [-01]).
12.2 Generator limit
"Generator switch-off limit"
The generator switch-off limit P534 [-02] has triggered.
• Reduce load on motor
• Set higher value in (P534 [-02]).
12.5 Load limit Switch-off due to overshooting or undershooting of
permissible load torques ((P525) … (P529)) for the time set
in (P528).
• Adjust load.
• Change limit values ((P525) ... (P527)).
• Increase delay time (P528).
• Change monitoring mode (P529).
12.8 Analog In minimum Switch-off due to undershooting of the 0% adjustment value
(P402) with setting (P401) "0-10V with switch-off on error 1"
or "....2"
12.9 Analog In maximum Switch-off due to overshooting of the 100% adjustment
value (P402) with setting (P401) "0-10V with switch-off on
error 1" or "....2"

E013 13.0 Encoder error No signal from encoder
• Check 5V sensor if present.
• Check supply voltage of encoder.
13.1 Speed slip error
"Speed slip error"
The slip speed error limit was reached.
• Increase setting in P327.
13.2 Shut-down monitoring The slip error monitoring has triggered; the motor could not
follow the setpoint.
• Check motor data P201-P209! (Important for the
current controller)
• Check motor circuit.
• In servo mode, check the encoder setting P300 and
check the following
• Increase setting value for torque limit in P112.
• Increase setting value for current limit in P536.
• Check deceleration time P103 and extend if
necessary
