How is this done?
• The VF controller in the operator is rated to operate on input frequencies ranging from 48Hz through
62Hz on 1Ø or 3Ø power (a jumper connection is required for phase change) but only on either
460VAC or 208V/230V. (A change between 460V and 230V, either direction, requires replacing the VF
controller).
• The control transformer in the operator is tapped for multiple voltages and rated for 50/60Hz
operation.
• The VF controller rst recties and lters the incoming power to DC, which has no frequency or phase.
It then creates 3Ø variable voltage/variable frequency AC for the motor from the DC.
• Depending on the model, the VF controller ramps the motor voltage and frequency from 0V@0Hz at
start, to either 208/230 or 460 VAC @ 60Hz for full speed. This allows use of 60Hz motors regardless of
the incoming frequency.
• Since the input voltage/frequency is converted to DC to begin with, there is absolutely no relationship
between the input frequency/phase and frequency/phase of the power supplied to the motor. The
input could be 1Ø or 3Ø, 48Hz or 62Hz and the controller/motor combination wouldn’t care. It will
create the ramped 3Ø voltage and frequency for which it is programmed.
NOTE: SlideDriver 50VF operators connected for 1Ø operation will draw more current because the utility power to run the machine
will be carried to the operator on two wires instead of the three used for 3Ø operators. Be sure to allow for this difference when
specifying wire size.
In-Field Connections
SlideDriver 50VF-series operators are eld re-connectable for 1Ø or 3Ø, 208/230VAC input power without
changing the VFD.
SlideDriver 50VF-series operators CANNOT be connected to 120V, 1Ø power or 575V, 3Ø power. If any attempts
are made to do so, serious injury, electrical shock, or death may result. Any electrical damage occurring to the
operator will not be covered by the Warranty.
SlideDriver 50VF-series operators are NOT eld recongurable between 208/230VAC and 460VAC power. The
VFD Motor Controller in a 208/230VAC unit must be replaced with a VFD Motor Controller manufactured for the
higher (460VAC) voltage input.
