Settings Function Description
0 No Function
Any unused terminals should be programmed to 0 to insure they
have no effect on operation.
1 Multi-Step Speed Command 1
These four inputs select the multi-speed defined by Pr.05.00 to
Pr.05.14 as shown in the diagram at the end of this table.
NOTE: Pr.05.00 to Pr.05.14 can also be used to control output
speed. There are 17 step speed frequencies (including Master
Frequency and Jog Frequency) to select for application.
2 Multi-Step Speed Command 2
3 Multi-Step Speed Command 3
4 Multi-Step Speed Command 4
5 External Reset
The External Reset has the same function as the Reset key on the
Digital keypad. After faults such as O.H., O.C. and O.V. are cleared
this input can be used to reset the drive.
6 Accel/Decel Inhibit
When the command is active, acceleration and deceleration is
stopped and the AC motor drive maintains a constant speed.
7
Accel/Decel Time Selection
Command
Used to select the one of 2 Accel/Decel Times (Pr.01.09 to Pr.01.12).
See explanation at the end of this table.
8 Jog Operation Control
Parameter value 08 programs one of the Multi-function Input
Terminals MI3 ∼ MI6 (Pr.04.05~Pr.04.08) for Jog control.
NOTE: Programming for Jog operation by 08 can only be done
while the motor is stopped. (Refer to parameter
Pr.01.13~Pr.01.15)
9
External Base Block
(Refer to Pr. 08.06)
Parameter value 09 programs a Multi-function Input Terminals for
external Base Block control.
NOTE: When a Base-Block signal is received, the AC motor
drive will block all output and the motor will free run. When base
block control is deactivated, the AC drive will start its speed
search function and synchronize with the motor sp
accelerate to Master Frequency.
10 UP: Increase Master Frequency
Increase/decrease the Master Frequency each time an input is
received or continuously when the input stays active. When both
inputs are active at the same time, the Master Frequency
increase/decrease is halted. Please refer to Pr.02.07, 02.08. This
function is also called “motor potentiometer”.
11
DOWN: Decrease Master
Frequency
12 Counter Trigger
Parameter value 12 programs one of the Multi-function Input
Terminals MI3~MI6 (Pr.04.05~Pr.04.08) to increment the AC drive’s
internal counter. When an input is received, the counter is
incremented by 1.
13 Counter Reset
When active, the counter is reset and inhibited. To enable counting
the input should be OFF. Refer to Pr.03.05 and 03.06.
14 External Fault
Parameter value 14 programs one of the Multi-function Input
Terminals MI3~MI6 (Pr.04.05~Pr.04.08) to be External Fault (E.F.)
inputs.
