Operation
H Internally-set Speed Selection
• The following table shows the relationship between SPD1 and SPD2 (speed selection commands 1
and 2), and the internally-set speeds that are selected.

Note 1. When Pn50A.0 (input signal allocation mode) is set to the default setting (0) and Pn000.1 is
set between 4 and 6, the control mode switches without TVSEL (control mode switching) sig-
nal allocation or input.
Note 2. When Pn50A.0 is set to 1 and the TVSEL signal is allocated, the control mode switches ac-
cording to the TVSEL signal.
