Danfoss VLT AQUA Drive FC 202

Name: Danfoss VLT AQUA Drive FC 202
Brand: Danfoss
SKU: 73bfabf2-f931-4b7e-8e34-49da94e7593a

Frequency converter for pumps and blowers in water and wastewater, with built-in PID and pump control.

The Danfoss VLT AQUA Drive FC 202 is a frequency converter that controls the speed of pumps and blowers in water supply and wastewater treatment. This Modbus RTU template reads frequency, current, power, temperatures, feedback and alarm words, and lets you start, stop and set the speed, ramps, limits and PID setpoints from ModbusCloud.

Protocol: Modbus RTU
Connection: RS485, 9600 baud
Registers: 1000, read and write

Brand: Danfoss
Key readings: Output frequency · Motor current · Motor power · DC link voltage · Heat sink temperature · Feedback value · Alarm and warning words · Running hours and energy
Available commands: Start, stop and reset · Speed reference · Ramp times · Speed limits · Closed-loop setpoints · Pump and application settings
Compatible models: VLT AQUA Drive FC 202

Send your device list

If a device is not in the library yet, we build the template for free as soon as we have the register data.

Use cases

Show frequency, motor current and power of every pump drive on one dashboard.
Send an email when the alarm word is not equal to 0, so a tripped pump is noticed straight away.
Keep a year of history of the feedback value and output frequency to see how a pressure station behaves.
Change the closed-loop setpoint or the ramp time of a pump from the portal without visiting the site.
Track running hours and the kWh counter per drive to plan maintenance and compare energy use.

Installation

Connect terminals 68 (P, A) and 69 (N, B) of the drive to A and B of the ModbusCloud Gateway, with termination at both ends of the bus.
Set parameter 8-30 Protocol to Modbus RTU and check address (8-31), baud rate (8-32) and parity (8-33); the defaults are 1, 9600 baud and even parity, 1 stop bit.
In ModbusCloud, add a Modbus RTU device on the Gateway with the same settings and import this template.
Check that Frequency, Motor Current and DC Link Voltage show plausible values.

Things to watch for

The drive does not answer on Modbus. What should I check?

Parameter 8-30 must be set to Modbus RTU; the default protocol is FC. Compare address, baud rate and parity in 8-31 to 8-33 with the device settings in ModbusCloud, swap A and B if nothing comes back, and check the bus termination switch on the drive.

How do I find the register of a Danfoss parameter?

The register number is the parameter number times ten, so parameter 3-41 is register 3410 and address 3409 in the template. The parameter number is in the comment of each register, so you can match it with the drive display or the programming guide.

Some array parameters always show the first value.

For array parameters, such as the alarm log, the drive returns the element chosen in Parameter Array Index. Write the index you want there first, then read the array parameter.

Can I start the pump or change the speed from ModbusCloud?

Yes, with the Bus Control Word and Bus Reference registers or the control word coils, and parameters such as setpoints and ramps are writable too. Writing registers from ModbusCloud is switched on per gateway on request. Coil 65 decides whether a written parameter is also stored in EEPROM; write only what you need.
