Temperature Error E10
Description
Possible Cause
Possible Countermeasures
After a certain operating time, the
dryve D1 enters the "Stop" state and
emits the error "E10 Temperature"
The power electronic is thermally
overloaded due to excessively
high Motor Current without any
regeneration time.
Inadequate temperature
management at the installation
location.
•
Load reduction
•
Motor Current reduction
•
Increase of the pause times
•
Use of a motor with a higher torque at the
same Motor Current
•
Improve heat dissipation
Following Error E11
Description
Possible Cause
Possible Countermeasures
In the case of a periodic movement
with acceleration and deceleration
phases longer that the movement at
uniform velocity, the dryve D1 enters
the "Stop" state after a certain
reproducible operating time and
outputs the error "E11 Following
Error".
The "
" used
for the acceleration and
deceleration phases is applied
without sufficient regeneration time
(current decreased to values
below the "
•
Boost Current reduction
•
Same acceleration and deceleration at a
lower Boost Current level
•
Shortened acceleration and deceleration
phases with same Boost Current
•
Increase of pause times between the
movements
•
Use of a motor with a higher torque at the
same Motor Current
•
Load Reduction
During acceleration or deceleration
phases or passages with an
increasing load, the dryve D1 enters
the "Stop" state and outputs the
error "E11 Following Error "
The motor rotor can no longer
follow the rotating field of the
stator. The difference between the
setpoint position and the actual
position (slip) cannot be
compensated within the specified
parameters.

Motor Current increase

Boost Current increase

Load reduction

Velocity reduction
Random motor direction
Description
Possible Cause
Possible Countermeasures
A stepper motor is changing
randomly the movement direction at
the movement start although a
constant direction is set. This
direction will be kept till the
movement is stopped.
The motor noise is “rougher” as
usual.
One of the four motor wires is
broken
•
Cut off the broken wire at the damaged
point and remove the insulation to
reattach it to the terminal
•
Exchange the cable
Error not resettable
Description
Possible Cause
Possible Countermeasures
The
error massage “E03 Encoder
Over-
current” will stay displayed
although no Encoder is attached
anymore and
the “Reset” button on
the user interface or Digital Input DI
10 “Stop/Reset” has been used.
The previous error condition (e.g.
external voltage supplied to X6
connector) has destroyed the
dryve D1 motor controller.
•
Buy a replacement for the broken motor
controller
