2 Description of Diagnostic Letters F... and E...
2.1 Error Diagnostic Messages
UL Motor Type not Reported
Description:
The settings for current regulation, velocity command, and position loop
are stored in the feedback of the motor. After powering up, the drive
compares the motor type stored in the parameters with the connected
motor type. If the two do not match, the drive remains at this state.
By pressing the S1 button, the drive overwrites its stored parameters with
the control loop parameters from the motor feedback.
Cause:
Motor was exchanged.
The parameter "P-0-4036, contacted motor type" from which the motor
type is selected would be loaded..
Remedy:
Command "C700 Basic Load” or press the S1 button.
PL Default Value of the Parameter Load
Description:
After the exchange of the product (EPROMs), if the parameters have
been changed in regards to the old product, the drive displays "PL". By
pressing the S1 button on the drive or through starting of the „command
load basic parameter", all the parameters will be erased and restored with
the default values.
Cause:
Product was exchanged and the number of parameters of the new
product has changed in regards to the old.
Remedy:
Press the S1 button on the drive controller and all the parameters will be
erased and restored with default values
WARNING
⇒ With this procedure all parameters and process
blocks will be overwritten.

In the DKC 01, this error can not occur because the input of the operating
mode will be tested when entered.
Remedy:
Input correct operating mode
F218 Heatsink Overtemperature Shutdown
Description:
The temperature of the DKC heatsink will be monitored. If the
temperature of the heatsink is too high, the drive will power down in order
to protect against damage.
Cause:
1. Ambient temperature is too high. The specified
operational data is valid up to an ambient temperature
of 45°C.
2. The DKC's heatsink is dirty.
3. Air flow is prevented by other assembly parts or a
control cabinet panel assembly.
4. Heatsink blower may be defective.
Remedy:

has been in operation for a long time, check to see if the
the operating conditions have changed. (in regards to
pollution, friction, moved components, etc.)
For 2. Check wires and cables to the motor temperature monitor for
wire breaks and short circuits.
For 3. Check velocity loop parameters.
F220 Bleeder Overtemperature Shut Down
Description:
The regenerated energy from the mechanism of the machine via the
motor has exceeded the power capability of the bleeder resistor. By
exceeding the maximum resistance energy, the drive will shutdown
according to the set error reaction. Thereby protecting the bleeder from
temperature damage.
Cause:
The reflected energy from the machine’s mechanism over the motor is
too large.
Remedy:
With too much power ---> reduce the acceleration value
With too much energy ---> reduce the velocity
Check the drive installation.
May require installation of an additional bleeder module.
F226 Undervoltage Error
Description:
The level of the DC bus voltage will be monitored by the drive controller.
If the DC bus voltage falls below a minimal threshold, the drive
independently shuts down according to the set error reaction.
Cause:
1. The power source has been interrupted without first switching off
the drive enable signal (RF).
2. Disturbance in the power supply
Remedy:
For 1 Check the logic regarding the activation of the drive within
the connected control.

DOK-ECODRV-ASE-02VRS**-WAR1-EN-P •07.96 Description of Diagnostic Letters F... and E... 2-5
F248 Low Battery Voltage
Cause:
The connected motor has an absolute encoder. The absolute position
information is stored in the motor feedback. This memory has a battery
powered backup for the electronic circuit. The battery is designed for a
operating life of 10 years. If the battery voltage drops below 2.8 V, this
message appears. The absolute encoder function is preserved for about
2 weeks.
Instructions for Exchanging Batteries
Have the following tools and accessories ready:
• Torx screwdriver,size 10
• Needle nose pliers, torque wrench
• New packaged battery (Part no.: 257101)
If the control voltage of the installed battery is turned off, the absolute
position is lost.
The absolute position must be re-established through the process of the
command Set Absolute Measurement.
F262 Status Outputs Short Circuited
Description:
If the status outputs of the DKC are short circuited, the drive controller will
issue an error.
Cause:
Short circuited outputs (X2/6, X2/7, X2/8, X2/9, X2/10, X2/20, X2/21,
X2/22)

F276 Absolute Encoder Error, Position Deviation > P-0-0097
Description:
When turning off the drive controller with a absolute encoder (multiturn),
the actual feedback position will be stored. When powered up, the
absolute position given by the encoder is compared to the stored
position. If the deviation is larger than the paramaterized "Absolute
Encoder-Monitoring Window", the error "F276, Absolute Encoder
Error" will appear and be given to the control system.
Cause:
1. Turning on for the first time (invalid stored position).
2. The motor was moved further than allowed by the parameter in
the absolute encoder monitoring window, P-0-0097, while it was
turned off.
3. Incorrect position initialization
Remedy:
For 1. Press S1 to reset the error and set the absolute position.
For 2. The motor was moved while turned off and sits outside of its
permissible position. Check to see if the displayed position is
correct in relation to the machine zero point. Reset subsequent
errors.
For 3. An accident may occur by accidental shaft movement.
Check absolute position informartion. A feedback defect is
present if the absolute position information is false. The motor
should be exchanged and sent to the INDRAMAT Customer
Service .

F879 Velocity Limit Value Exceeded (S-0-0092)
Description:
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.
Remedy:
Check the primary control loop.
see also the "Velocity Monitoring in Torque Control" function description
F895 4 kHz Signal Error
Description:
The 4kHz signal is synchronized with the software processing for creation
of the resolver signal. This error message is created when
synchronization occurs improperly.
