•
The same holds for Relative Positioning commands, where the sum of
the commanded pos the start position should be less than the
maximum allowed position.
•
Check the position limit values . Moreover, the positive position limit
value must be greater than the negative position limit value.
•
If you don’t need the position limit check, de-activate it, e.g. in modulo
mode.

E255 Feedrate-override S-0-0108 = 0
With the parameter S-0-0108, Feedrate override , the travel velocity of all
drive-controlled travel commands can be changed proportionally (in %). If
the value of this parameter is 0, the travel velocity is also 0. With velocity
= 0, the motor remains stationary despite having a commanded value.
Cause:
1. The parameter S-0-0108, Feedrate override is 0.
2. For devices with analog inputs: Feedrate override via analog input is
activated, and the voltage at the analog input is 0.
3. The feed potentiometer of the connected control system is at 0 or is
being evaluated incorrectly.
Remedies for:
1. Set Feedrate override > 0 , so that the drive moves. Full speed is
attained with 100 %.
2. Apply a voltage > 0 proportional to the desired speed, +10 V
corresponds to 100 % (full) speed. Alternative: De-activate Feedrate
override.
3. Turn the feed potentiometer cautiously, check the analog signal and
the evaluation for it.

E257 Continuous current limit active
The thermal controller work load is monitored. If a command current
profile is demanded from the drive controller and this profile is too high a
load for the power transistors in the long run (too high temperature rise of
the power output stage), the drive reacts by dynamically reducing the
effective peak current. While doing this, this warning is output. The
parameter
P-0-4046, Active peak current is reduced. Before this real
peak current limitation occurs, the pre-warning E261 Continuous current
limit pre-warning should have been generated.
Cause:
The drive controller has been overloaded.
Remedy:
1. Check the amplifier dimensioning.
2. Reduce the acceleration.
3. Check the sense of rotation of the motor encoder.
