Value Function Description
38 PID integral disabled
When the terminal set for this function becomes on, the integral function
becomes disabled. However, the proportional and differentiation
functions are still effective.
 Switchover between main frequency
reference and preset frequency
When the terminal set for this function becomes on, the frequency
reference is replaced by the preset frequency set in F0-08.
40 Switchover between auxiliary
frequency reference and
preset frequency
When the terminal set for this function becomes on, the frequency
reference is replaced by the preset frequency set in F0-08.
41 Motor selection
Switchover between the two groups of motor parameters can be
implemented through the two state combinations of the terminal set for
this function.

43 PID parameter switchover
If PID parameters switchover is done via DI terminal (FA-18 = 1), the PID
parameters are FA-05 to FA-07 when the terminal set for this function
becomes off; the PID parameters are FA-15 to FA-17 when the terminal
set for this function becomes on.
44 8VHUGHÀQHGIDXOW
If the terminals selecting these two functions become on, the AC drive
reports Err27 and Err28 respectively, and performs fault protection

This function enables the AC drive to switch over between speed
control and torque control.
When the terminal set for this function becomes off, the AC drive runs
in the mode set in A0-00.
When the terminal set for this function becomes on, the AC drive
switches over to the other control mode.
47 Emergency stop
When the terminal set for this function becomes on, the AC drive
immediately stops as fast as possible. During the stop process, the
current remains at the set upper limit. This function aims at satisfying
the applications where emergency stop is required.
48 External stop 2
This function enables the AC drive to decelerate to stop in any control
mode (operation panel, terminal or communication). In this case, the
deceleration time is deceleration time 4.

50 Clear the current running time
When the terminal set for this function becomes on, the current running
time of the AC drive is cleared. This function must be supported by F8-
42 and F8-53.

Three-wire control mode
This function enables the AC drive to switch over between two-wire
control mode and three-wire control mode. If F4-11 is set to two-wire
control mode 1, the AC drive switches over to three-wire control mode 1
when the terminal set for this function becomes on.
52 Reverse running prohibited
When the terminal set for this function becomes on, reverse running of
the AC drive is prohibited. It is the same as the function of F8-13.
