VFD Parameter Pre-Setting for Pump Manufacturers

VFD parameter pre-setting should start from verified motor and pump data. Create one approved baseline per compatible pump package, record every changed value and verify the configuration in production. Pre-setting reduces field work only when installers can still adjust site-specific values safely.

What Information Is Required?

• Motor voltage, current, frequency, speed and type.
• Minimum and maximum pump speed.
• Acceleration, deceleration and direction.
• Sensor type, units, setpoint and PID behavior.
• Dry-run, overload, restart and communication rules.
• Settings locked for production versus adjustable on site.

Selection Example

For a constant-pressure booster, pre-set motor data and safe speed limits, then configure the intended pressure input and sleep/wake logic. Leave the site pressure target clearly documented if it must be commissioned locally.

Common Mistakes

• Copying parameters from another motor.
• Hiding site-specific assumptions.
• Changing defaults without a revision number.
• Locking settings installers must adjust.
• Verifying parameters but not pump operation.

AUSENIST Solution

AUSENIST can prepare and control basic YS620/YS820 parameter sets for approved OEM packages. Final pressure, hydraulic limits and site behavior must be commissioned on the actual system.
