Example 4: Forward Run/Reverse Jog
This example shows an application in which the drive runs full-speed forward and
jogs in reverse. The full scale of the potentiometer will be used.
Note: When calculating the values for the Analog Input using reverse motion, the
reverse frequency reference should be shown using a negative (-) number. Pay special
attention to signs (+/-) for values representing reverse motion.
• Minimum Frequency Reference = -15Hz (reverse)
• Maximum Frequency Reference = 60Hz
Calculations

Note: The negative (-) value for the Analog Offset % shows that a negative offset is
needed for 4-01.

Parameter Settings
4-01: 2 – Negative Input Offset Polarity
4-02: 25 – 25% Analog Input Offset
4-03: 125 – 125% Analog Input Gain
4-04: 1 – Reverse Motion Enable
