OPTIONAL: Automatic calculation of the speed controller parameters
From version 12.00.00 onwards: Following successful motor parameter identification, the speed
controller parameters listed in the below table can also be calculated automatically.
• If these parameters are to be calculated, bit 6 of C02865/1
must be set to "5".
• Care must be taken that the constant
mass inertia of the drive (mass inertia of motor, gearbox,
shaft and constant load) is entered as exactly as possible in C00273
to calculate the speed
controller parameters as dynamically as possible.
• Mass inertias that are not constant (e.g. changing loads of reels or different loads of hoists)
must be entered in C00919/1
.
• If the mass inertia set in C00273
is too low, the speed controller parameters are calculated
less dynamically.
• If the mass inertia set in C00273
is too high, speed controller operation is unstable.
• If the mass inertia in C00273
is set to "0", the setting of bit 5 in C02865 has no effect on the
speed controller parameter calculation. In this case, the speed controller parameters will not be
calculated automatically after motor parameter identification.
OPTIONAL: Automatic calculation of other controller parameters
From version 12.00.00 onwards: Following successful motor parameter identification, the controller
parameters listed in the below table can also be calculated automatically.
• If these parameters are to be calculated, bit 6 of C02865/1
must be set to "6".
