10. Troubleshooting and Maintenance
10-5
⑤
Is PAR_17 [motor speed] properly set?
☞
check the motor nameplate and setting matches.
⑥
Is PAR_22 [motor rated current] properly set?
☞
check the motor nameplate and setting matches.
⑦
Is PAR_27 [motor flux current] properly set?
☞
If LG-OTIS vector motor is not used, consult LS representative or set the correct value in accordance with
application. However, it cannot set to exceed PAR_22 [motor rated current]. Normally it is 30~40 % of rated
motor current.
⑧
Is PAR_21 [motor rated slip] properly set?
☞
check the motor nameplate and setting matches.
⑨
Is PAR_28 [Motor secondary time constant (Tr) properly set?
☞
if motor is not LG-OTIS vector motor, perform the Auto-tuning or set this correctly. If it is incorrectly set,
inverter performance will be dramatically deteriorated.
⑩
Is PAR_19 [number of motor poles] properly set?
☞
check the motor nameplate and setting matches.
⑪
CON_33 [Torque limit setting] is set to
“
Kpd Kpd Kpd
“
. Is CON_34 ~ CON_36 setting correct?
☞
CON_34 ~ CON361 marks upper limit in inverter output torque. For the application lower torque limit is
required, when torque shortage occurs, increase this value a little. STARVERT
-
iV5
‘
s overload capacity is
150%/1 min. when using torque limit over 150%, time and the number of use should be limited.
⑫
When CON_33[torque limit setting] Analog or Option, the corresponding input value is properly set?
☞
CON_33 is set to Analog, one of Ai1/Ai2/Ai3 should be defined as
“
Torque limit
”
. If set to Option, refer
to Option manual for proper setting.
3) Motor speed is not increasing while it is running.
①
Is PAR_10 [number of Encoder pulse] set properly?
☞
factory default is 1024. If it is not OTIS vector motor, contact with Encoder maker.
