(b) For full-closed loop control
Note that when using machine side detector, some parameters must be set depending upon
linear scale and installation conditions.
[1] Set SV025 bit8 to B(ent) by following the motor side detector specification as for the
linear scale and installation conditions.
[1] Set SV025 bit8 to B(ent) by following the motor side detector specification as for the
semi-closed loop control.
[2] When polarities of the motor side detector and machine side detector do not match, set
SV017 bit4=1.

Set the detector type.
Set the position detector type for “pen”, and the speed detector type
for “ent”. In the case of the semi-closed loop control, set the same
value for “pen” and “ent”.
