Figure 80: Motor potentiometer example
If a minimum frequency has been configured (P-02), the motor potentiom-
eter will always start at f = 0 Hz. After the configured minimum frequency is
exceeded, the motor potentiometer will work within the range up to the
maximum frequency (P-01). The frequency will not fall below the minimum
frequency value unless the start enable (DI1) is switched off.
