25 Parameter Lock (Write disable, Read is always 0)
This function will disable the write function and all the content of read are 0. The application
is for customer having a key to control the operator to modify parameters or modify the
parameter by improper use.
26 PID Disable (N.O.) / 27 PID Disable (N.C.)
This function pause the PID control. It is commonly used for manual operation or function
testing, and to recover the PID function when the system is normal.
28 Second Source of Frequency Command
This function is used with Pr. 142 to select a different frequency source for control.
29 Forward (contact is open) / Reverse (contact is close)
This function has top priority to set the direction for running (If “Pr. 24 inhibit REV function”
is not set). No mater what the present direction of run is, the contact N.O. is forward and
the contact N.C. is reverse, once this function is set.
The requirement for setting direction is Pr. 24 > setting 29 of Pr. 39-Pr. 42 > Pr. 38.
31 Index Input Signal
This function is used with parameters 149 to 151. The position where AC drive stops will be
regarded as the zero position and it will move to the angle that Pr. 150 sets.
32 Counter Incremented by Drive Output Frequency
This function is for counting at the speed of the output frequency.
Note: The settings 00~32 in Pr. 39 to Pr.42 can be used to set multi-function terminals
(M2-M5) but the settings cannot be used repeatedly at the same time (besides
settings 20).
