Frequency setting by external terminals

PARAMETERS

4.6 Frequency setting by external terminals

4.6.1 Multi-speed setting operation (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)

The above parameters allow its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.

*The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)

(1) Multi-speed setting (Pr. 4 to Pr. 6)

⋅Operation is performed at the frequency set in Pr. 4 when the RH signal turns ON, Pr. 5 when the RM signal turns

ON, and Pr. 6 when the RL signal turns ON.

Purpose Parameter that must be Set Refer to Page

Make frequency setting by

combination of terminals Multi-speed operation Pr. 4 to Pr. 6, Pr. 24 to Pr. 27,

Pr. 232 to Pr. 239 93

Perform Jog operation Jog operation Pr. 15, Pr. 16 95

Added compensation for multi-speed

setting and remote setting

Multi-speed input

compensation selection Pr. 28 97

Infinitely variable speed setting by

terminals Remote setting function Pr. 59 98

Can be used to change the preset speed in the parameter with the contact terminals.

Any speed can be selected by merely turning ON-OFF the contact signals (RH, RM, RL, REX signals).

Parameter

Number Name Initial

Value Setting Range Description

4 Multi-speed setting (high speed) 60Hz 0 to 400Hz Set the frequency when RH turns ON.

5 Multi-speed setting (middle speed) 30Hz 0 to 400Hz Set the frequency when RM turns ON.

6 Multi-speed setting (low speed) 10Hz 0 to 400Hz Set the frequency when RL turns ON.

24 *Multi-speed setting (speed 4) 9999 0 to 400Hz, 9999

Frequency from speed 4 to speed 15 can

be set according to the combination of

the RH, RM, RL and REX signals.

9999: not selected

25 *Multi-speed setting (speed 5) 9999 0 to 400Hz, 9999

26 *Multi-speed setting (speed 6) 9999 0 to 400Hz, 9999

27 *Multi-speed setting (speed 7) 9999 0 to 400Hz, 9999

232 *Multi-speed setting (speed 8) 99 99 0 to 400Hz, 9999

233 *Multi-speed setting (speed 9) 99 99 0 to 400Hz, 9999

234 *Multi-speed setting (speed 10) 9999 0 to 400Hz, 9999

235 *Multi-speed setting (speed 11) 9999 0 to 400Hz, 9999

236 *Multi-speed setting (speed 12) 9999 0 to 400Hz, 9999

237 *Multi-speed setting (speed 13) 9999 0 to 400Hz, 9999

238 *Multi-speed setting (speed 14) 9999 0 to 400Hz, 9999

239 *Multi-speed setting (speed 15) 9999 0 to 400Hz, 9999

REMARKS

⋅In the initial setting, if two or three speeds are simultaneously sele cted, priority is given to the set frequency of the lower signal.

For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.

⋅The RH, RM, RL signals are assigned to the terminal RH, RM, RL in the initial setting.

By setting "0 (RL)", "1 (RM)", "2 (RH)" in any of Pr.178 to Pr.189 (input terminal function assignment), you can assign the signals to

other terminals.
