VFD
The space currently has 2 Variable Frequency Drives; these magic boxes provide 3 phase AC power to 3 phase motors from the single phase mains of the space.
Machines that use a VFD
- The power saw has a HYOD
- The CNC Mill has a newer HYOD.
VFD Control
The power saw VFD doesn't really need settings changing for normal operation.
The CNC Mill controller interfaces with the CNC Mill VFD through PWM (0-10v) to adjust things like spindle speed, and direction.
VFD Parameters
Most VFD have a set of around 500 PD values that allow you to change settings on the unit (such as drive frequency); changes to these PD values can fry motors and/or the VFD. These PD values should only need to be set once, tailored to the application for the VFD and never would normally need to be changed by anyone but a service engineer.
