4.3 Multi-function Digital Input Settings (H1-XX) (continued)
Setting
MOP Adjust Increase
84
Closed: The MOP ratio adjustment is increased. See P2-02 and P2-09.
MOP Adjust Decrease
85
Closed: The MOP ratio adjustment is decreased. See P2-02 and P2-09.
MOP Adjust Reset
86
Closed: The MOP ratio adjustment is reset to zero. See P2-02 and P2-09.
Position Error Reset
Closed: Position regulator error is reset to zero.
87
Note: ELS modes only.
Position Regulator Integral Reset
Closed: Position regulator integrator is reset to zero.
88
Note: ELS modes only.
Align by Pulse (Alignment)
Closed: Alignment function is enabled and the drive will keep the number
of quadrature follower encoder counts (displacement) between the master
89
and follower alignment inputs equal to the displacement reference.
Note: ELS modes only.
Save Displacement
Closed: At the transition from open to closed, the current Displacement
Reference value (which can be seen in the Displacement Reference
monitor U1-94) will be saved to the Initial Alignment Displacement
Parameter (P4-01). The data will survive a power loss.
8A
Note: ELS modes only.
Note: Since this command saves the data into non-volatile RAM, do not
continuously use this function. The drive's storage RAM could fail causing
drive failure.
Disable Displacement Error
Closed: Displacement error will not be corrected. However, if the Align by
Pulse (Alignment) digital input (H1-XX = 89) is closed, the displacement
feedback will still be calculated and displayed (U1-95), but the follower
8B
drive will not correct for any displacement error. This input is useful for
troubleshooting and testing.
Note: ELS modes only.
