The motor encoder signals are monitored. If the signal amplitudes as measured via AK1 and AK2 are outside of the allowable region between Uss = 12.0V and Uss = 18.0 V, then the error message appears. The drive becomes torque-free and an optional brake is immediately activated.This error can only be cleared in parametrization mode (phase 2). As a result of this error, the encoder emulation is switched off.

The current in the power transistor bridge has exceeded twice the peak current of the drive. As a result, the drive will be immediately turned off. The drive has switched to a torque-free condition. An optional brake is immediately activated.

The DKC requires a 24V control voltage.

 If the maximum allowable tolerance of +- 20% is exceeded, then the drive is immediately switched to torque free operation. An optional brake is activated. Cause: Disturbance or overload of the 24 V supply voltage. Measure control voltages

The actual velocity is monitored in torque regulation mode. This error is generated if the programmed velocity in the "S-0-0091, bipolar velocity limit value" parameter is exceeded by 1.25 times or a maximum of 100 Rpm. Cause: The load torque was smaller or larger than the torque command value for too long a time. This leads to an increase in the actual velocity up to the maximum possible motor velocity

The velocity loop monitor will appear 

when the following conditions occur simultaneously: • The current command value is at the peak current limit • The difference between the actual velocity and the command velocity is larger than 10% of the maximum motor velocity. • actual speed > 1.25% of maximum speed • command and actual acceleration have different qualifying signs Cause: 1. Motor cable is connected incorrectly. 2. Defective controller section of the drive. 3. Defective feedback. 4. Velocity loop paramaterized incorrectly. 5. Incorrect commutation offset
