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.

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
