VFD
- The Variable Frequency Drive (VFD) converts the AC supply voltage to DC and then con
verts the DC to a suitable three-phase frequency source for Ml. Incoming power connects to ter
minals LI & L2. Ml connects to terminals Tl, T2, & T3 through TSI. The HMC sends the com
mand to the ModBus to set the frequency for the combination of ovens selected. The VFD can re
ceive a signal from the fire suppression system to command the drive to run at 60 Hz. A complete
