Why there is continuous variation in output frequency of a Hitachi Inverter L Series? But there is a third option for source frequency which is a constant frequency and it takes the value from a parameter. The applicable motor refers to Hitachi standard 3-phase motor 4-pole. Page of 12 Go. Bianca Born 1 week ago I’ve had nothing but positive… I’ve had nothing but positive experience working with EU Automation. Comments to this Manuals Your Name. But still I don’t know why was it varying up and down when the source frequency was potentiometer.

It’s often less irritating to spread the noise across a spectrum than it is to output a single tone. The users who hitaachi to close gave this specific reason: I want to have the fixed speed after i set it from the keypad Potentiometer.

Page 8 L Inverter Specifications Derating curves, continued Please tell hitacui why it is varying and how can i reduce it or make it to run at constant speed. It may simply be noise in the analog-to-digital conversion. Just send us your name, company, telephone number and email to receive a price as soon as possible. The applicable motor refers to Hitachi standard 3-phase motor 4-pole.
Choosing a higher carrier frequency tends to decrease audible noise, but it also increases the internal heating of the inverter, thus decreasing derating the maximum current l10 capability.
Try to use the keypad buttons to set the frequency instead of potentiometer and see if there is a difference. Thanks for your message. A variation of a couple tenths of a percent may not be unusual.
