Parameter
5. In external mode, when PO is
‘
on
’
, the programmed operation mode is chosen. Terminal STF becomes
the start signal. When STF is
‘
on
’
, the inverter begins to run in programmed operation mode at the first
section. When STF is
‘
off
’
, the inverter stops running, and STR becomes the pause signal. When STR
is
‘
on
’
, the inverter pauses and continues to run at the section where the inverter paused when STR is
‘
off
’
. For details, please refer to P.100, P.101~P.108, P.111~P.118, P.121~P.123 and P.131~P.138.
6.
In external mode, when MPO is
‘
on
’
, the
manually operation
circle mode is chosen.
For details,
please refer to P.100, P.101~P.108, P.111~P.118, P.121~P.123 and P.131~P.138.

Note: 1. measurement of stator resistance:
440v series: Set value=measured value of resistance meter/2
220v series: Set value=measured value of resistance meter/3
2. When the inverter runs, the auto-upgraded voltage results in
greater torque.
0: Auto-voltage upgrade is disabled.
1: Auto-voltage upgrade function is valid, we can use this
function to compensate the changes of the frequency when the
load of the motor becomes heavier.
