E. Data 34 : Up/Down Function
Programming data " 34 " for n39 (multi-function input terminal) allows the S4 / S5 inputs to be used
for Up/Down frequency setting.
NOTES:
1. Parameter n38 will not be valid when n39 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:
n09 (Fmax) x
n30 (Freq. Ref. Upper Limit)
100
5. Lower limit speed is from n31 , Frequency Reference Lower Limit.
6. See section 5.10 for information on the Up/Down hold memory.
