ECODRIVE03 SMT-02VRS Description of diagnostic letters F... and E... 3-27
DOK-ECODR3-SMT-02VRS**-WA01-EN-P
Note: Warning E247 is suppressed if S-0-0259, Positioning Velocity
is cyclically configured.

Interpolation"
E248 Interpolation acceleration = 0
Cause:
The drive internal position command interpolator (profile generator) is
active. It has been given the acceleration = 0. Without acceleration, it can
never reach a given speed.
Note: Input parameter values are converted into a drive internal
format, so an input acceleration word > 0 can, when
converted, result in an acceleration = 0. The parameter values
which, internaly, result in an acceleration > 0, can be
calculated using the formulas found in the chapter entitled
"Drive-internal format of position data"
Operation modes with drive internal position command generation:
1. Drive-internal interpolation
2. Relative drive-internal interpolation
3. Drive-controlled homing
4. Drive Halt
5. Process block mode
6. jog
Remedy:
Input a reasonable value > 0 for the employed acceleration. Possible
acceleration specifications, depending from the operation mode, are:
For 1, 2 and 6: S-0-0260, Positioning acceleration >0
For 3.: S-0-0042, Homing acceleration >0
For 4.: S-0-0138, Bipolar acceleration limit value >0
For 5.: P-0-4008, Process block Acceleration >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. Relative drive-internal interpolation
3. Positioning Block Mode
4. Jogging
