- - - STR Reverse rotation start
(can be assigned to STR
terminal (Pr. 63) only)
*1 When Pr. 59 = "1 or 2", the functions of the RL, RM and RH signals change as
listed above.
*2 Actuated when the relay contact "opens".
*3 When using the REX signal, an external command cannot be used to make a
reverse rotation start.
REMARKS
•
One function can be assigned to two or more terminals. In this case, the function
is activated when one of the multiple terminals used for assignment turns on.
•
The speed command priorities are higher in order of jog, multi-speed setting (RH,
RM, RL, REX) and AU.
•
Use common terminals to assign multi-speeds (7 speeds) and remote setting.
They cannot be set individually.
(Common terminals are used since these functions are designed for speed
setting and need not be set at the same time.)
