(D) Operation command and frequency command Parameters
5 - 290
Input compensation of multi-speed setting (Pr. 28)
Speed (frequency) compensation can be applied for the multi-speed setting and the remote setting
by inputting the frequency setting compensation signal (terminals 1, 2).
NOTES The priority of the frequency commands by the external signals are "Jog operation > multi-speed
operation > terminal 4 analog input > pulse train input > terminal 2 analog input". (For details on
frequency commands by analog input, refer to page 5-401.)
Valid in the External operation mode or PU/External combined operation mode (Pr. 79 = "3" or "4").
Multi-speed parameters can also be set during PU operation or External operation.
The Pr. 24 to Pr. 27 and Pr. 232 to Pr. 239 settings have no priority among them.
When Pr. 59 "Remote function selection" ≠ "0", the multi-speed setting is invalid since the RH, RM,
and RL signals are for remote setting.
When performing analog input compensation, set Pr. 28 "Multi-speed input compensation selec-
tion" to "1".
Select the terminals (terminals 1, 2) to use for compensation input voltage (0 to ± 5 V, 0 to ± 10 V)
at Pr. 73 "Analog input selection".
When using terminal 1 for compensation input, set Pr. 868 "Terminal 1 function assignment" to "0"
(initial value).
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may
affect the other functions. Set parameters after confirming the function of each terminal.
