Commissioning the motor model
The thermal I2t motor model is activated via p0612.0 = 1, the expansions of the motor model
can additionally be activated via p0612.8 = 1.
Note
When commissioning the motor, thermal motor model 1 (p0612.0 = 1) including expansion
(p0612.8 = 1) is automatically activated.
Preconditions for automatic activation:
•
Use of a permanent magnet synchronous motor
•
There is no motor sensor
•
No (other) thermal motor model is activated
Important settings
The most important parameters for thermal motor model 1 and/or for the expansion of this
model are subsequently explained.
When the expansion is subsequently activated, the corresponding parameters of the
expansion are preassigned with the parameter values before activating the expansion.
Parameters for the following
settings
