Emotron VS10 - Tuning of the Motor and the Speed Controller

156 01-6203-01R3, CG Drives & Automation
7.4.1.1. Tuning of the motor and the speed controller
The following describes in general how to optimise the speed controller. This may be
required if some parameters have on the load side of the drive system have changed or
have not been set yet, such as:
• Motor moment of inertia
• Load moment of inertia
• Type of coupling between moment of inertia of the motor and that of the load
Preconditions
• All rated motor data are known and set in the inverter manually.
 Manual setting of the motor data  108
• All further options for optimisation have been executed before if possible.
 Automatic motor identification (energized)  139
 Automatic motor calibration (non-energized)  140
• Optimisation is possible online or offline (with or without connected motor).
Required steps
Adapt the following parameters to your drive system using the engineering tool. Since this
only changes load-dependent data, the other parameter groups must not be calculated
again.

Setting of the moment of inertia of the load.
Always adjust the setting to the current load, otherwise the
optimisa
tion process cannot be executed successfully.
