F03

Following error message of the position controller (in  OPMODE 5 or 6 only)

Axis is mechanically tight or blocked

Check the mechanical system

Check the mechanical system

Inadequate torque for the ramps set

Travel along flatter ramps (ACC, DEC)

Travel along flatter ramps (ACC, DEC

Ramps in the velocity controller are longer than ramps in the position controller 

Lower the acceleration ramp(ACC) and braking ramp (DEC) in the velocity controller

Lower the acceleration ramp (ACC) and braking ramp (DEC) in the velocity controller

Amplifications set too low. Axis is too undynamic 

Adjust the amplification, Velocity Loop and possibly Position Loop screen pages

Adjust the amplification, Velocity Loop and possibly Position Loop 

Amplifications set too high. Axis oscillates. 

Adjust the amplification, Velocity Loop and possibly Position Loop screen pages, use filters 

Adjust the amplification, Velocity Loop and possibly Position Loop screen pages

IPEAK (maximum current) too low

Enlarge following error window (Position Data) or use a larger amplifier / motor, increase IPEAK .
