Data 34 : Up/Down Function
Programming data " 34 " for n056 (multi-function input terminal) allows the S6 / S7 inputs to be
used for Up/Down frequency setting.
NOTES:
1. Parameter n055 will not be valid when n056 is set to " 34 ".
2. Jog has priority over Up/Down.
3. Up/Down has priority over Multi-step Frequency inputs.
4. Upper limit speed is set by the formula:
n011
(Fmax) x n033 (Freq. Ref. Upper Limit)
100
5. Lower limit speed is from n034 , Frequency Reference Lower Limit.
6. See section 5.10 for information on the Up/Down hold memory.
