current P0320 entered. The motor data identification routine should then be re-started by
calling P1900 = 2 or P1900 = 3.
A step-by-step description is given in section "Quick Commissioning".
Parameter settings
WARNING
The motor data identification routine MUST not be used for loads which are potentially
hazardous (for example, suspended loads for crane applications). Before the motor data
identification routine is started, the potentially hazardous load must be carefully secured (for
example, by lowering the load to the floor or by clamping the load using the motor holding
brake).
Parameter Description
P0625 = … Ambient motor temperature (entered in °C)
The motor ambient temperature is entered at the instant that motor data is being determined (factory set-
ting: 20 °C).
The difference between the motor temperature and the motor ambient temperature P0625 must lie in the
tolerance range of approx. ± 5 °C.
If not the motor must be allowed to cool down.
P0010 = 0
Commissioning parameter filter*
Check if P0010 = 0 (Ready)
P1900 = 3 Select motor data identification*
0: Disabled (default)
2: Identification of all parameters in standstill.
3: Identification of all parameters in standstill including saturation curve
ON command Start motor data identification
Once P1900 ≠ 0, alarm A0541 is generated that states, the next ON command will initiate the motor data
identification. When the ON Command is given, current flows through the motor and the rotor aligns itself.
Note: When motor data identification is complete A0541 will be cleared and P1900 will be set to zero.
OFF1 In order to set the inverter into a defined state, an OFF1 command must be issued before the next step.
With the OFF1 command the motor data identification is finished.
