Position coder method orientation stop position
6531 3031 3031 4031
Data unit : 1 pulse (360 degrees/4096)
Data range : 0 to 4096
Standard setting : 0
This parameter specifies the stop position of position coder method
orientation. For spindle orientation of stop position external setting
type or incremental command external setting type, this parameter is
invalid. Instead, the stop position command (SHA11 to SHA00),
which is a input signal, becomes valid.

Upper limit of spindle orientation speed
6538 3038 3038 4038
Data unit : 1 min
–1
Data range : 0 to 32767
Standard setting : 0
This parameter specifies the upper limit of orientation speed at the
spindle end. If 0 is set in this parameter, the motor magnetic flux
down start speed (parameter No. 4103) converted for the spindle side is
assumed.

Velocity loop proportional gain on orientation (HIGH) CTH1A=0
6542 3042 3042 4042
Velocity loop proportional gain on orientation (LOW) CTH1A=1
6543 3043 3043 4043
Data unit :
Data range : 0 to 32767
Standard setting : 10
These parameters specify velocity loop proportional gains on
orientation.

6551 3051 3051 4050
Data unit :
Data range : 0 to 32767
Standard setting : 10
These parameters specify velocity loop integral gains on orientation.
