Description of Functional Parameter
5
C27 SPI delay setting limits：2S～255*1.28S factory default：8S
Set speed loss protecting action standard with unit of 1% and AC drive
rated current 100%.
C23 rotation moment of force test setting limits：0 ～4 factory default：0
0： without over moment of force testing
1： test only in constant speed, it continue running after testing
2： test during running, it continue running after testing
3： test only on constant speed, AC drive is “OFF” after testing
4： test during running, AC drive output “OFF” after testing
Set it to be 2 or 4 to test over rotation moment of force during accelerating or
retard.
Set it to be 1 or 2 to keep it running after testing over rotation moment of force.
Operator displays “OL3”(flashing) alarm during testing.
Set it to be 3 or 4 to temporary stop AC drive during over rotation
moment of force testing. Operator displays “OL3” error(light on) during testing.
Over rotation moment of force testing time:If the time of motor current surpassing
rotation moment of force testing standard(C24) is longer than testing time(C25),over
rotation moment of force testing function works.
Set input phase missing test grade, with unit of 1%, DC400V (200V grade)
and DC800V(400Vgrade) to be 100%.
C25 over rotation moment of force setting limits：0.1S～10.0S factory default：0.1S
C26 SPI standard setting limits：1%～100% factory default：20%
Input phase missing test time test time=1.28sec×（C27's value）
Set output phase missing test grade, with unit of 1%, AC drive rated
C28 SPO standard setting limits：1%～100% factorydefault：0%
Over rotation moment of force test standard: set over rotation moment of force
testing current standard with unit of 1%.
C24 rotation moment of force standard setting limits：30%～200.0% factory default:160%
current to be 100%.

Electronic overheat protection is monitoring motor temperature to protect it
form overheat by simulate of AC drive output current/frequency and time. When
electron overheat relay is functioning it gives “OL1” report and cut off AC drive
output to avoid motor overheat. If there is only one motor connected to a AC
drive, external heat relay in not needed. If more than one motor is connected to
a AC drive, each motor need to install heat relay and set constant(C19)to be “0”.
C20 retard and speed loss setting limits：0～1 factory defaut：1
0：without speed loss protection function during retard
1：with speed loss protection function during retard
C21 accelerating standard setting limits：30%In～200.0%In factory default：*3
Set speed loss protecting action standard with unit of 1% and AC drive
rated current 100%.
C22 running standard setting limits：30%In～200.0%In factory default：*3
