Setting
48 Speed measuring input SM2 (only for X5)
The functions are explained as follows:
1~3: MS terminals
If any three of F7.00~F7.04 are set at 1, 2, 3 respectively, Up
to 8 segments of speed can be defined through the
combination of the ON and OFF state of the 3 terminals.

The MS frequency will be used in MS running and simple
PLC operation. Let's see an example:
Set the parameters corresponding to X1, X2 and X3:
F7.00=1, F7.01=2, F7.02=3, then X1, X2 and X3 are used to
perform MS running. See Figure 5-38.

By combination of the ON/OFF state of Terminal 1 and 2,
you can get 4 groups of Acc/Dec time.
6~7: External fault signal (normally-open/close input)
If the setting is 6~7, fault signal of external equipment can be
input via the terminal, which is convenient for the drive to
monitor the fault of external equipment. Once the drive
receives the fault signal, it will display "E015". The fault
signal has two input modes, i.e. normally-open and
normally-close.
Figure 5-40 Normally-open/close input
In Figure 5-40, X4 is normally open input and X5 normally
close input. KM is external fault relay.
8: Reset
If any of F7.00~F7.04 is set at 8, the drive can be reset via
Time
the terminal when the drive has a fault. The function of this
terminal is the same with the RESET key on the keypad.
9~10: External jog command (JOGF/JOGR)
If any of F7.00~F7.04 is set at 9~10, the terminal can enable
the jog operation. JOGF is terminal for forward jog operation
command and JOGR is terminal for reverse jog operation
command. Jog frequency, jog interval and jog Acc/Dec time
are defined in F3.13~F3.16.
11: Coast to stop
This function is the same with F2.08, however, it is realized
by terminal and convenient for remote control.
12~13: Frequency increase (UP) /decrease (DN)
If the setting is 12~13, the terminal can be used to increase
or decrease frequency instead of
for remote control. This terminal is valid when F0.00=1 or
F9.01=2. Increasing or decreasing rate is determined by
F7.09.
14: Pause command for simple PLC
If the setting is 14, the terminal is used to pause the PLC
operation and the drive operates at zero frequency when the
terminal is enabled, but the running time is not counted. If
the terminal is disabled, the drive will start at start frequency
