V/F pattern
Pr. 14
Setting
RT(X17) Signal Output Characteristics
(4) Change load pattern selection using
terminal (Pr. 14 = "4, 5")
⋅ Output characteristic can be switched between for
constant torque load and for elevator using the RT
signal or X17 signal.
⋅ For the terminal used for X17 signal input, set "17"
in any of Pr. 178 to Pr. 189 (input terminal function
selection) to assign the function.
When X17 is assigned, switchover by the RT signal
is invalid.
4
ON
For constant torque load
(same as when the setting
is "0")
OFF
For elevators at reverse
rotation boost of 0% (same
as when the setting is "2")
5
ON
For constant torque load
(same as when the setting
is "0")
OFF
For elevators at forward
rotation boost of 0% (same
as when the setting is "3")
REMARKS
⋅ The RT signal is assigned to the terminal RT in the initial setting. By setting "3" in any of Pr. 178 to Pr. 189 (input terminal function
selection), the RT signal can be assigned to the other terminal.
CAUTION
⋅ When Advanced magnetic flux vector control, Real sensorless vector control or vector control is selected, this parameter setting
is ignored.
⋅ 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. When the RT signal is ON, the other second functions are also valid.
