Frequently Asked Questions
Q1: I powered up the drive but the fan isn't spinning. Is it broken?
Don't worry - probably not. The GD28 uses smart temperature control. The fan won't spin below 36°C, and only runs at full speed above 69°C. If the heatsink feels warm but not hot, it's working normally. Still concerned? Check parameter P08.41 (setting the tens digit to 1 forces temperature-controlled mode on).
 
Q2: How do I wire this STO function? I see two terminals.
The GD28 uses dual-channel redundant STO (two safety circuits backing each other up), TÜV-certified to SIL3. Factory default has STO1 and STO2 shorted to +24V. To use it: Remove those two shorting wires, connect two normally-closed safety contacts, and both channels need +24V simultaneously for the drive to run.
 
Q3: I'm getting E23 or E8 errors. What do they mean?
E23 (Motor Overheat): Either the motor is genuinely hot, or the temperature sensor isn't connected right. The DI4 terminal on GD28 can accept a PTC thermistor. Don't forget - there's a DIP switch on the control board that needs to be switched to "PTC" side.

E8 (Overvoltage): This usually means you're stopping too fast. Solutions: Increase deceleration time (P00.12) or for loads with inertia, use a braking resistor (all GD28 models have the braking unit built-in).
 
Q4: No computer on site. What's the easiest way to copy parameters to another drive?
Easiest way is the official parameter copier (looks like a USB stick). Budget-friendly trick: Use an OTG cable + Type-C with your Android phone. Plug into any Android phone, open the "INVT Debug Assistant" app, read parameters, save them, upload to another drive.
 
Q5: I need Profinet to talk to my PLC. Does this drive support it?
Yes. GD28 comes standard with Modbus RTU. For Profinet, EtherCAT, or EtherNet/IP, you need to buy and plug in an optional expansion card.
