5.8 Stop Modes Selection

F7.10
0: Decelerate to Stop
After the stop command is enabled, the inverter decreases the output frequency according to the
deceleration time and stops when the frequency decreases to zero.
1: Coast to Stop
After the stop command is enabled, the inverter immediately stops the output. The motor will coast to stop
due to the mechanical inertia.

5.9 Observation of Operation Status via DO and AO

5.9.1 Digital Output DO
JT550 series inverter comes standard with two digital output terminal Y1, Y2 (Y2 which can be used as
high-speed pulse output DO), 2 relay outputs R, E, 2 analog outputs AO1, AO2 (can be selected as the
current output).
F3.00 Y2/DO Terminal Output Mode
Y2 / DO terminal is re-programmable terminals and can be used as high-speed pulse output terminal
(DO). It also can be used as an open-collector terminal (Y2) of digital output.
0: Pulse Output (FMP)
1: Switch Signal Output (FMR)
When DO is set as a pulse output, the maximum frequency of the output pulse is 100kHz. To see more
DO-related functions, please refer to Note F3.06.

Relay E Output Function Selection
F3.04
Defined digital output terminal Y1, Y2 and relay R, E functions. When Y2/DO terminal is the high-speed
pulse output, configure its settings in F3.06 rather than F3.02.
5.9.2 Analog Output AO
F3.10
F3.11
These parameters correct the zero drift of analog output and the output amplitude deviation. They can
also be used to customize the desired AO curve.
If "b" represents zero offset, "k" represents the gain, "Y" represents the actual output, and "X"
represents the standard output, then the actual output is: Y = kX + b.
The zero offset coefficient 100% of AO1 and AO2 corresponds to 10 V (or 20 mA). The standard
output refers to the value corresponding to the analog output of 0 to 10 V (or 0 to 20 mA) with no zero offset
or gain adjustment.
For example, if the analog output is used as the operating frequency, and it is expected that the output
is 8 V when the frequency is 0 and 3 V at the maximum frequency, the gain shall be set to -0.50, and the
zero offset shall be set to 80%.
