User Manual of EM760 High-Performance Inverter This mode is mainly used when the motor can rotate. However, loads should be avoided or minimized; otherwise, self-learning will have poor effects. 1. Motor parameter self-learning is valid only in the keyboard-controlled start/stop mode (F00.02=0): Set F01.34 to the corresponding value, and press the OK key for confirmation and then the RUN key to start motor parameter self-learning. After the parameter self-learning, F01.34 of the inverter will be automatically set to 0; 2. Please do perform parameter self-learning once before running with FVC drive control, so as to reach better results of control; 3.
If there is an overcurrent or overvoltage fault during self-learning, extend the acceleration and deceleration time and try again. 4. Before self-learning with the encoder, you must set correctly the encoder type (F01.24), encoder line count (F01.25) and the number of rotary transformer pole pairs (F01.30, set only when F01.24=4). Parameters related to phase sequence (F01.27 - F01.28) can be either set manually or acquired via self-learning. 5. The first group ofmotor parameters is taken as an example above. For the second group ofmotor parameters, refer to the above description. 7.3.2 Parameter Self-identification of Synchronous Motor F01.34=10 :
not identified There are 3 self-learning methods for the synchronous motor. You can make your option based on the working conditions. However, you must perform once the self-learning of motor parameters upon new installation or replacement of the motor. In case ofSVC drive mode, you can perform “12 rotary self-learning” or “11 static self-learning”, and manually input the counter electromotive force (F01.22); and in case of FVC drive mode, you can perform “ 13 encoder self-learning” alone. However, “12 rotary self-learning” should be carried out additionally if you wish to further enhance control performance. F01.34=11 :
the synchronous motor remains stationary during parameter self-identification. Prior to the static self-learning ofthe synchronous motor, please set the motor type (F01.00) and motor nameplate parameters (F01.01 to F01.05) correctly. Relevant parameters (F01.19 to F01.21) of the synchronous motor and current loop parameters (F06.12 to F06.15) can be obtained during static self-learning. This mode is mainly used when the motor cannot rotate. It is necessary to manually enter the counter electromotive force (F01.22). 214 Function code Function codename Parameter description Unit Default setting Attribute F01.34 Motor parameter self- learning 10: No operation 11:
