4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used Speed Bias Function •This function applies speed command bias in the pulse train position control mode. •Set a bias value in frequency addition amount A145, and select a sign in frequency addition direction A146. •Allocate 50 (ADD) to any of the multi-function inputs. While the ADD terminal is turned on, the bias value is added to the speed command. Speed bias A145 ADD terminal Position bias 4 P024 Set with A146.
+/- Functions Position command variation Position control Speed control Speed feedback value Position feedback variation Orientation Function •This function determines a motor position at a single desired point during one rotation of the motor, and can be used to exchange tools for the machine tool main spindle or others. •During positioning, the Z-pulse (one rotation position signal) is used as the reference signal. Input Z-pulse between EZP and EZN. 4-125 Related functions A145, A146 Parameter No. Function name Data Default setting Unit P011 Encoder pulses 128. to 9999./1000 to 6553 (10000 to 65530) 1024.
