User Manual of EM760 High-Performance Inverter The magnitude of injection component of excitement current can be set for F06.29 and F06.33. F06.51 is the switching parameter with hysteresis used by the synchronous motor SVC during start-up. 7.2.2 Synchronous motor FVC control In case of synchronous motor FVC control, it’s recommended to select UVW encoder as far as possible and rotary transformer. If a regular incremental encoder is selected, the initial position will be identified automatically during the first run upon power-on. All steps are the same as the asynchronous motor FVC control except that synchronous motor encoder self-learning is selected for self-learning.
7.3 Motor Parameter Self-identification 7.3.1 Parameter Self-identification of Asynchronous Motor F01.34=0 : not identified F01.34=1 : the asynchronous motor remains stationary during parameter self-identification. Prior to the static self-learning of the asynchronous motor, please set the motor type (F01.00) and motor nameplate parameters (F01.01 toF01.08) correctly. Relevant parameters (F01.09 toF01.13) of the asynchronous motor can be obtained during static self-learning. This mode is mainly used when the motor cannot rotate. Static self-learning has poorer effects than rotary self-learning. F01.34=2 : the asynchronous motor rotates during parameter self-identification.
Please disengage the load. Prior to the rotary self-learning of the asynchronous motor, please set the motor type (F01.00) and motor nameplate parameters (F01.01 toF01.08) correctly. Relevant parameters (F01.09 toF01.18) of the asynchronous motor can be obtained during rotary self-learning. This mode is mainly used when the motor can rotate. However, loads should be avoided or minimized; otherwise, self-learning will have poor effects. F01.34=3 : the asynchronous motor rotates during encoder parameter self-identification. Please disengage the load. Please connect the encoder first.
Prior to the encoder self-learning of the asynchronous motor, please set the motor type (F01.00), motor nameplate parameters (F01.01 toF01.06), and encoder parameters - F01.24, F01.25 and F01.30 - correctly. Encoder self-learning allows you to acquire parameters related to the asynchronous motor such as F01.09 to F01.18 while judging current conditions of the encoder. 213 Function code Function codename Parameter description Unit Default setting Attribute F06.51 Synchronous motor open-loop until SVC switching frequency 0.0~50.0 % 2.5 O Function code Function codename Parameter description Unit Default setting Attribute F01.34 Motor parameter self- learning 0: No operation 1:
