Revision 10/2005, BE13, SW V4.08 5-59
Settings Function Description
00 No Function
ny unused terminals should be programmed to 0 to insure they
have no effect on operation.
01 Multi-Step Speed Command 1
02 Multi-Step Speed Command 2
03 Multi-Step Speed Command 3
04 Multi-Step Speed Command 4
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 by programming the AC motor drive’s internal
PLC function. There are 17 step speed frequencies
(including Master Frequency and Jog Frequency) to select
for application.
05 External Reset (N.O.)
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.
06 Accel/Decel Inhibit
When the command is active, acceleration and deceleration is
stopped and the AC motor drive maintains a constant speed.
07
Accel/Decel Time Selection
Command 1
08
Accel/Decel Time Selection
Command 2
Used to select the one of four Accel/Decel Times (Pr.01-09 to
Pr.01-12, Pr.01-18 to Pr.01-21). See explanation at the end of
this table.
09
External Base Block (N.O.)
(Refer to Pr. 08-06)
10
External Base Block (N.C.)
(Refer to Pr. 08-06)
Parameter values 9, 10 program 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
speed, and then accelerate to Master Frequency.
11 UP: Increment Master Frequency
12
DOWN: Decrement Master
Frequency
Increment/decrement 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
increment/decrement is halted. Please refer to Pr.02-08, 02-09.
This function is also called “motor potentiometer”.
13 Counter Reset
When active, the counter is reset and inhibited. To enable
counting the input should be OFF. Refer to Pr.03-08 and 03-09.
14 Run PLC Program
To run the AC motor drive internal PLC program.
NOTE: Pr.05-00 to Pr.05-16 define the PLC program.
15 Pause PLC Program
When the PLC program runs, a Multi-Function Input Terminal,
when set to 15, can be used to pause the PLC program.
