How Do You Configure Preset Speeds on ATV630 and ATV930 Drives?
Resolution:
You can set preset speeds on ATV630 and ATV930 drives by assigning digital inputs and defining the corresponding speed values.
✅ Basic Setup Steps
-
Go to:
Main Menu → Complete Settings (CST) → Generic Functions → Preset Speeds -
Assign preset speed inputs:
- Assign digital inputs (DIx) to preset speed selection (for example, DI1, DI2, DI3).
-
Set the speed values:
- Define each preset speed (e.g., SP2, SP3, SP4, etc.) in Hz based on your application.
-
Activate preset speeds:
- When the assigned digital inputs change state, the drive automatically switches to the corresponding preset speed.
Preset speeds are selected using a binary (ON/OFF) combination of digital inputs:
- Each digital input represents a binary bit (0 = OFF, 1 = ON).
- Up to 16 preset speeds are supported depending on the number of inputs configured.
- The combination of ON/OFF states determines which preset speed is active.
- Preset speeds override the normal speed reference when active.
- Always verify input assignments to avoid unintended operation.
The manual contains a truth table that explains which inputs need to be On/Off for multiple Preset Speeds to work. See the attached excerpt from the manual.
