Allen-Bradley PowerFlex 70 Reference Manual

Speed Reference 2-173
For example, to send out a command frequency of 60 Hz with [Maximum
Freq] = 70 Hz, we would calculate the following:
Jog
When the drive is not running, pressing the HIM Jog button or a
programmed Jog digital input will cause the drive to jog at a separately
programmed jog reference. This speed reference value is entered in [Jog
Speed], parameter 100.

Scaling
Scaling applies only to references from analog inputs and reference sources
selected in [Speed Ref x Sel], parameters 90/93.
Each analog input has its own set of scale parameters:
• [Analog In x Hi] sets the maximum level on input to be seen (i.e. 10
Volts).
• [Analog In x Lo] sets the minimum level on input to be seen (i.e. 0
Volts).
Each [Speed Ref x Sel] parameter has an additional set of scale parameters:
• [Speed Ref x Hi] selects the reference value for the maximum input
specified in [Analog In x Hi].
• [Speed Ref x Lo] selects the reference value for the minimum input
specified in [Analog In x Lo].
