ARTDrive V2 series - Instruction Manual Chapter 8 Appendix • 357
- Drive sized too small
- Incorrect V/f characteristics set
Motor decelerates too slowly
Ramp value incorrectly set
Motor turns slowly, although reference value = Zero
Minimum speed logic active
Unused speed reference configured to an open analog input. Remedy: set source
parameters for any unused speed reference to OFF.
Main speed referece source is an analog input: disconnect reference value on
used analog input,
- if drive now stands still, the effect is due to the cable resistance of the 0V
cable.
- if the drive is still turning: carry out offset compensation of the analog input.
The speed during acceleration with maximum current is not linear
Reduce the Speed integral gain and proportional gain proportionally. If this
does not lead to an improvement, retune the speed regulator.
Speed oscillating
Speed regulator integraI gain vs proportional gain ratio is too high.
Motor potentiometer function not executed.
When operating with remote keys: D09.00 - Mpot up src and/or D09.01 - Mpot
down src and D09.02 - Mpot invers src were not mapped to digital inputs or
LAN channel bits.
Jog operation not possible
A start command is still present.
When operating with remote keys: JD10.01 - Jog cmd src and/or D10.04 - Jog
invers src were not mapped to digital inputs or LAN channel bits
Internal speed reference values not actuated
D08.00 - Mlt spd s 0 src, D08.01 - Mlt spd s 1 src or D08.02 - Mlt spd s 2 src
were not mapped to digital inputs or LAN channel bits
Multi-Ramp function not reacting
D01.00 - Mlt ramp s0 src or D01.01 - Mlt ramp s1 src were not mapped to
digital inputs or LAN channel bits.
