Description
| The parameter EXTPOS define the source of feedback used for the position loop. For EXTPOS = 0 the motor feedback, defined by the command FBTYPE, will used for the position loop. For EXTPOS > 0 an external feedback will used for position loop. The gearing factor of the external feedback to bring the external position to 32Bit per revolution will set by the parameter EGEARO as a multiplier and EGEARI as a divisor. If EXTPOS is set to negative values the feedback is read and the position stored in PFB0. The position loop acts with the commutation feedback (FBTYPE). example: EXTPOS = -6 The sinus/cosinus-Feedback(5V) is read. The position can be monitored by ASCII-command PFB0. The input of the external feedback is withput effect to the position control. EGEARI and EGEARO can be used to set the ratio: 1. On all analog read position feedbacks EXTPOS=6,7,8,9 the position is calculated by the ENCLINES-setting and converted to the 32Bit/turn -format. The parameter EGEARI/EGEARO are only for the gearing-factor. On EGEARI-feedback turn the motor makes EGEARO turns. example: EGEARI=10,EGEARO=3 -> ratio 10 : 3 2. On all digital read position feedbacks( EXTPOS=1...4 ) the parameter ENCIN defines the feedback pulses / turn. The parameter EGEARI/EGEARO sets the gearing-faktor. example: An external digital Encoder has got 1024 pulses / turn, on 1 feedback turn the motor runs 3 turns. The necessary settings are: EXTPOS 3, ENCIN 1024, EGEARI 1, EGEARO 3 |
