7.69 (ID 418) Motor Potentiometer Up
Location in the menu:
• INU application: P3.3.4.1 and P3.5.1.23
Use this parameter to increase the output frequency with a digital input signal. With a motor potentiometer, it is possible to in-
crease and decrease the output frequency. When a digital input is connected to parameter Motor Potentiometer UP, and the digital
input signal is active, the output frequency rises. The motor potentiometer reference INCREASES until the contact is opened.
7.70 (ID 419) Preset Frequency Selection 1
Location in the menu:
• INU application: P3.3.3.9 and P3.5.1.20
Use this parameter to select the digital input signal that is used as a selector for the preset frequencies. This parameter is a binary
selector for Preset speeds (0–7). See parameters P3.3.3.1 to P3.3.3.8.
You can use the Preset frequencies function in processes where more than 1 fixed frequency reference is necessary. There are 8
preset frequency references available.
To apply Preset frequencies 1 to 7, connect a digital input to these functions with the instructions in
Inputs.
7.71 (ID 420) Preset Frequency Selection 2
Location in the menu:
•
INU application: P3.3.3.10 and P3.5.1.21
Use this parameter to select the digital input signal that is used as a selector for the preset frequencies. This parameter is a binary
selector for Preset speeds (0–7). See parameters P3.3.3.1 to P3.3.3.8.
You can use the Preset frequencies function in processes where more than 1 fixed frequency reference is necessary. There are 8
preset frequency references available.
To apply Preset frequencies 1 to 7, connect a digital input to these functions with the instructions in
Inputs.
