J. Up/Down Control ( 29 ): Up/Down Function
Programming data "Up/Down Control" (" 29 ") for n040 (multi-function input terminal)
allows the inputs to be used for Up/Down frequency setting.
NOTES:
1.
Parameter n039 will display " –– " when n040 is set to "Up/Down Control" (" 29 ").
2. Jog has priority over Up/Down.
3. Up/Down has priority over Multi-step Frequency inputs.
4. Up/Down is ineffective when operation is from the Digital Operator.
5. Upper limit speed is set by the formula:
n011(Fmax) x
n031(Freq. Ref. Upper Limit)
100
6. Lower limit speed is either the reference from external terminals FV or FI,
or from n032, Frequency Reference Lower Limit, whichever is higher.
7. Upon a Forward (or Reverse) Run command, the drive will operate at the
lower limit speed, until an UP command is given.
