How to use the input signals
(assigned terminals DI1 to DI4, STR)
1.8 How to use the input signals (assigned terminals DI1 to DI4, STR)
(Pr. 180 to Pr. 183, Pr. 187)
These terminals vary in functions with the settings of Pr. 180 to Pr. 183 and Pr. 187.
The priorities of the speed commands are in order of jog, multi-speed setting (RH, RM, RL, REX) and PID (X14).
1.8.1 Multi-speed setting (RL, RM, RH, REX signals): Pr. 180 to Pr. 183, Pr. 187 setting
"0, 1, 2, 8"
Remote setting (RL, RM, RH signals): Pr. 180 to Pr. 183, Pr. 187 setting "0, 1, 2"
• When Pr. 59 = 0, turning on/off the RL, RM, RH and REX signals input as the speed commands enables multi-
speed operation (15 speeds). (Refer to page 77 for details. Pr. 59 = 0)
• When Pr. 59 "0", you can use contact signals to perform continuous variable-speed operation without using
analog signals even if the control panel is away from the control box. (Refer to page 103 for details.)
1.8.2 Second function selection/second motor switchover (RT signal)
: Pr. 180 to Pr. 183, Pr. 187 setting "3"
1.8.3 Jog operation (jog signal):
Pr. 180 to Pr. 183, Pr. 187 setting "5"
(1) Jog operation using external signals
Jog operation can be started/stopped by shorting the jog mode select terminal JOG-SD and shorting/opening the
start signal terminal STF or STR-SD. The jog speed and jog acceleration/deceleration time are set in Pr. 15 (factory
setting 150r/min, variable between 0 and 1500r/min) and Pr. 16 (factory setting 0.5s, variable between 0 and 3600s
(when Pr. 21 = 0)/0 to 360s (when Pr. 21 = 1)), respectively, and their settings can be changed from the control
panel or parameter unit.
The jog signal has higher priority than the multi-speed signals. (external)

Entering the RT signal enables the second functions (above parameters). However, when Pr. 450 = 9999, it is
judged that the second motor functions are not selected, and parameters Pr. 451 and Pr. 453, Pr. 454 are invalid.
The second functions other than the above are enabled with the first motor.
