2-16 SA3100 Drive Configuration and Programming
2.4 Configuring the Volts per Hertz (V/Hz) Regulator
The following sections (2.4.1 to 2.4.5) describe the parameter entry screens for the
SA3100 Volts per Hertz regulator. These screens are accessed by selecting SA3100
as the product type and Volts per Hertz as the regulator type when configuring the
UDC module. If your drive uses the Vector with Constant Power regulator refer to
section 2.3.
The parameter screens are set up to provide a good starting point with the volts per
hertz characteristic when the Enable Tuning command (register 100/1100, bit 1,
PMI_TUN@) is issued. You can tune this curve by running the motor unloaded and
monitoring motor current when going through the frequency range of interest. The
curve should be modified to minimize current consumption/transients when going
through the frequency range of interest.
2.4.1 Power Module Data Screen (Volts per Hertz)
The Power Module Data screen allows you to enter specific information about your
power system configuration and the type of Power Module being used. See figure 2.9.
Power System Configuration
• DC Input Voltage or AC input Voltage
Select the type of input line voltage (AC input or DC input) and then enter the input
voltage value.
Select DC Input Voltage if this is the DC bus voltage. Select AC Input Voltage if this
is the AC RMS voltage that is being converted to DC bus voltage. This voltage
determines which group of Power Modules may be selected from the Part Number
list. The default selection is DC Input Voltage.
