Invertek E3 2.2 KW IP20

Model: ODE-3-220105-1F42

Manual

SETUP – This is general information for typical CNC use.    For 3DTek CNC machines please follow the more application-specific information in our build instructions.

• You must have an electrician setup this device – its dangerous.
• You and your electrician must read the manual, the notes below are to assist in configuring the VFD for our spindles not to instruct on safe installation for which the manual must be consulted.
• To setup the VFD to operate 3 phase spindles, you must set the ‘Important Config Parameters’ listed below.
• The ‘Other Useful’ Parameters can generally be ignored unless further functionality is required for your setup – such as G Code Control.

 

Important Config Parameters

 

Parameter P‐01: Maximum Frequency / Speed
Set to 400 (HZ) or 24000 RPM for our 3 phase spindles, or the rated frequency of your own motor.  Depending on your setting in P10 this may need to be set in HZ or RPM.

 

Parameter P‐02: Minimum Frequency / Speed
Set to 25 (HZ) (1500RPM) for our 3 phase spindles, they don’t like running very low RPM

 

Parameter P‐07: Motor Rated Voltage
Set to 220 (V) for our 3 phase spindles, or the rated voltage of your own motor

 

Parameter P‐08: Motor Rated Current
Set to 10 (A) for 2.2KW spindles, 7 (A) for our 1.5KW spindles, 4 (A) for our 800W spindles.

 

Parameter P‐09: Motor Rated Frequency
Set to 400 (HZ) for our 3 phase spindles, or the rated frequency of your own motor.

 

Parameter P‐10: Motor Rated Speed
Set to 24000 (RPM) for our 3 phase spindles, or the rated speed of your own motor.

 

Parameter P‐12: Terminal / Keypad / PID Drive Control Mode Selection
0. Terminal control   (Using the IO Terminals (G Code Spindle Control)
1. Keypad control – fwd only (Using Keypad for Spindle Control

 

Parameter P‐14: Extended Menu Access Code
Set to 201 to allow access to all parameters

 

Parameter P‐51: Motor Control Mode
Set to 1 for VF mode.

Other Useful Config Parameters

 

Parameter P-15: Digital Input Function Select
0. Spindle run mode whenever DI1 (T2) is @ 24V.
This value is only valid / relevant only when parameter P-12 = 0!

 

There are other functionalities available, see table 7.3. Terminal mode in manual for more options.  These parameters are useful when looking to control spindle operation through G-code or other advanced configurations.   Analogue Input 1 in these scenarios receives the 0-10V input for spindle speed.   Common grounds between your controller (AIO/MASSO/GECKO) and the VFD are important – connect the GND (0V) terminals of these devices together

 

If you wanted the spindle to always be in run mode and only react to speed G-codes (S commands) on the 0-10V input (AI1 /Terminal 6) then you would set P-15 to 0 and short terminals 1 (24V) , & 2 (DI1) with a wire. 

If you wanted to use both S commands for speed and also M3 (ON FWD)  & M5 (OFF) commands for start stop you would need to set P-15 to 0 and offer T2 (DI1) a 24V Signal to turn the spindle on in a clockwise direction and disconnect it to stop. The AIO uses TTL Logic outputs and so you would need to run a TTL coil relay to connect 24V to T2 (DI1). The Masso has transistor switches so you can connect 24v from the VFD to Masso’s Spindle Pin 5, and Spindle pin 4 to the VFD’s T2(DI1).

 

Parameter P18: User Relay Output Function Select for controlling pumps or other…
0 : Drive enabled (On when when the drive is enabled (Running))
1 : Drive healthy (On when relay when drive is powered up and ready)
2 : Motor at target speed (On when motor up to speed not for coolant pumps!)
…etc

For example, to instruct the spindle cooling pump only to run when the spindle is running, you could set P18 to 0.
