5.2.3 Parameter modifications (TRACTION)
The parameters can be modified with the chopper standby or running. In the latter
case, you must return to standby before switching off the chopper so that the modifica-
tions are stored in the chopper’s nonvolatile memory.
1 ACCELER.DELAY Acceleration time
2 BRAKING Braking current - base value
3 CUT BACK SP.1 1st speed reduction
4 CUT BACK SP.2 2nd speed reduction
5 CUT BACK SP.3 3rd speed reduction
6 AUXILIARY TIME Time delay to activate the auxiliary function
7 COMPENSATION Compensation for speed reductions
8 BRAKING MODUL. Braking current increment in inversion with accelerator
9 IMAX. Maximum chopper current
10 MAX SPEED FORW Maximum forward speed
11 MAX SPEED BACK Maximum backward speed
12 CREEP SPEED Minimum acceleration threshold
13 WEAK DROPOUT Weakening output current threshold
14 CURVE BRAKING Curve braking current (RV1)
15 CURVE TIME Curve braking time
16 BACKING TIME Time delay to activate the back request, 9 = continuous
A detailed description of these parameters is given on point 5.1.3.
