Up/Down Control - Omron M1 Series User Manual

If "161: ADD" is not allocated to the multifunction input terminal, or if the ADD terminal is ON, add or
subtract Frequency Addition Amount (301FHex-23Hex). If the ADD terminal is turned OFF, the addi-
tion or subtraction of Frequency Addition Amount (301FHex-23Hex) is canceled, and the inverter
returns to the status of the selected frequency reference.
Parameter No.

Note 1. If the sign of the frequency reference changes (from (-) to (+), or from (+) to (-)) as a result of the calcula-
tion, the rotation direction is reversed.
Note 2. When the PID function is used, this function is enabled even for the PID target value. The value is added
in increments of 0.01% where the Frequency Addition Amount (301FHex-23Hex) with respect to the tar-
get PID value is taken to be 100%. At this time, if a value larger than 100.0 is set, the limit is set at
100.0.

UP/DOWN control

Use this function to change the inverter output frequency via the multifunction input terminals UP and
DWN.

• When the RUN command is turned ON, the frequency reference when the previous RUN command
is OFF is output. To operate from 0 Hz when the RUN command is ON, set UP/DOWN Control Initial
Value Selection (3008Hex-3EHex) to 0.
• Commands from the UP and DWN terminals are enabled only when the RUN command is ON. The
frequency reference is added when the UP terminal is ON. The frequency reference is subtracted
when the DWN terminal is ON. Addition and subtraction of the frequency reference is stopped when
both are ON. When either of the terminals is OFF, the frequency reference is added or subtracted
according to the command from the ON terminal.
