Frequency reference FWD (REV) Run/Stop Multi-step Speed Ref. 1 Multi-step Speed Ref. 2 Multi-step Speed Ref. 3 Jog Reference Figure 5.9 Preset Reference Timing Diagram u d2: Frequency Upper/Lower Limits By entering upper or lower frequency limits, the drive programmer can prevent operation of the drive above or below levels that may cause resonance and or equipment damage. n d2-01: Frequency Reference Upper Limit Sets the maximum frequency reference as a percentage of the maximum output frequency. This limit applies to all frequency references.
Even if the frequency reference is set to a higher value, the drive internal frequency reference will not exceed this value. Parameter Details n d2-02: Frequency Reference Lower Limit Sets the minimum frequency reference as a percentage of the maximum output frequency. This limit applies to all frequency references. If a lower reference than this value is input, the drive will run at the d2-02 level. If the drive is started with a lower reference than d2-02, it will accelerate up to d2-02. 5 Operating range Frequency Reference Upper Limit Frequency Reference Lower Limit Set frequency reference Figure 5.10 Frequency Reference:
