DOK-DIAX04-ELS-06VRS**-WA01-EN-P
Operation modes with drive internal position command generation:
1. Drive-internal interpolation
2. Drive-controlled homing
3. Drive Halt
4. Jog
Remedy:
Input a reasonable value > 0 for the employed acceleration. Possible
acceleration specifications, depending from the operation mode, are:
For 1.and 4.: S-0-0260 , Positioning acceleration >0
For 2.: S-0-0042, Homing acceleration >0
For 3.: S-0-0138, Bipolar acceleration limit value >0

Interpolation"
E249 Positioning velocity >= S-0-0091
Cause:
Operating modes with internal interpolation limit the positioning speed to
that set in
S-0-0091, Bipolar velocity limit value.
This applies to the following modes:
1. Drive Internal Interpolation
2. Jogging
Remedy:
S-0-0259, Positioning Velocity or
P-0-4030, Jog velocity
must be reduced

Interpolation".
E250 Drive overtemp. prewarning
The temperature of the heatsink in the drive controller has reached the
maximum permissible temperature. The drive controller follows the
command value input for a period of 30 seconds. This makes it possible
to bring the axis to a standstill with the control system while keeping true
to the process (for example, close the operation, leave the collision area,
etc.).
After 30 seconds, the response set in parameter P-0-0119, Best
possible deceleration will be performed by the drive controller.
Cause:
1. Failure of the drive’s internal blower.
2. Failure of the control cabinet’s climate control.
3. Incorrect control cabinet sizing in regards to heat dissipation.
Remedy for:
1. If the blower fails, exchange the drive controller.
2. Install climate control feature in the cabinet.
3. Check the sizing of the control cabinet.
