What to check if Gefran Inverter displays SS1 Digital input Stop command?
If a Gefran Inverter displays an 'SS1 Digital input Stop command' error, it could be due to:* 08-30 =0 and 03-00~03-07=58.To resolve this:* Check if 08-30 =0 and 03-00~03-07=58.
What causes FB PID feedback loss on Gefran Inverter?
If a Gefran Inverter displays an 'FB PID feedback loss' error, it could be due to:* Feedback signal wire broken.* Feedback sensor broken.To resolve this:* Check feedback wiring.* Replace feedback sensor.
How do I fix CE communication error on Gefran Inverter?
If a Gefran Inverter displays an 'CE communication error', it could be due to:* Connection lost or wire broken.* Host stopped communicating.To resolve this:* Check connection.* Check host computer / software.
What to do if Gefran Inverter displays run Switch for Motor1/ Motor2 error?
If a Gefran Inverter displays an 'run Switch for Motor1/ Motor2' error, it could be due to:* Executing a command for switching motor2 in running time.* Executing a command for switching motor in running time.To resolve this:* Revise the sequence control and switch motor in top time.
What causes DEV Speed deviation on Gefran Inverter?
If a Gefran Inverter displays an 'DEV Speed deviation' error, it could be due to:* Load being too heavy.* Mechanical brake active preventing motor from turning.* PG wiring error.* PG parameters (group 20) set incorrectly.* Acceleration / deceleration time set to short.To resolve this:* Check load.* Make sure brake is released.* Check PG wiring.* Check PG parameters 20-23/20-24.* Increase Acceleration / deceleration time.
How to fix OC over current on Gefran Inverter?
If the Gefran Inverter displays an 'OC over current' error, it could be due to several reasons:* Acceleration or deceleration time being too short.* A contactor being present on the inverter's output side.* The motor being used is either a special type or its size exceeds the inverter's rated capacity.* A short circuit or ground fault.To resolve this, try the following:* Extend the acceleration or deceleration time.* Check the motor wiring.* Disconnect the motor and attempt to run the inverter.
What causes OS Over speed on Gefran Inverter?
If a Gefran Inverter displays an 'OS Over speed' error, it could be due to:* Motor speed overshoot (ASR).* PG ppr set incorrectly.* Overspeed parameters set incorrectly.To resolve this:* Check ASR parameters group 21.* Check PG parameters.* Check overspeed parameters 20-20/20-12.
What does UT Under torque detection mean on Gefran Inverter?
If a Gefran Inverter displays an 'UT Under torque detection' error, it could be due to:* Sudden drop in load.* Belt break.To resolve this:* Check under torque detection parameters (08-19 / 08-20).* Check load / application.
What causes OT Over torque detection on Gefran Inverter?
If a Gefran Inverter displays an 'OT Over torque detection' error, it could be due to:* Load being too heavy.To resolve this:* Check over torque detection parameters (08-15 / 08-16).* Check and reduce the motor load, also check the operation duty cycle.
