Introduction
The Jain C3+ Platform can remotely control and monitor the Danfoss FC Series Variable Frequency Drives for synchronous and asynchronous motors.
The installation of the VFD is not detailed in this article, installation should be carried out by a qualified electrician. This article focuses on the interface between the C3+ and Danfoss VFD. Jain will provide support ONLY for the C3+ configuration (though note that the MODBUS map below MUST be followed).
Remote control capability should not replace local on/off control or any other fail-safe hardware. An Emergency Stop button and appropriate power disconnects should always be in place at the same location as the VFD.
Application
As part of a Jain system, the device can show:
- Status
- Pressure
- Faults
- Energy Consumption
- Output Frequency
- Power
- Pressure Setpoint
- Drive Mode
- Remote Mode
Supported Models
VLT® AQUA Drive FC 202
Electrical Connection and Installation
Connection to the VFD is via the C3's RS485 MODBUS port. The field unit should be located as close as possible to the controller.
System Protection
Please note that Jain do not take any responsibility for the safety and protection of the system. This is assumed to be the responsibility of the VFD. Any further protection requirements above those provided by the VFD are the responsibility of the installer.
Configuring the Danfoss Panel
The VFD acts as a MODBUS Slave device with the C3+ as the Master. The following must be set on the Danfoss panel for communication:
- 8-30 Protocol: [2] Modbus RTU
- 8-31 Address: 1
- 8-32 FC Port Baud Rate: [3] 19200 Baud
- 5-10 Terminal 18: [8] Run/Stop
- 8-01 Control Site: [0] Digital and Ctrl. Word (Control by using both digital input and control word)*
- 8-33 Parity / Stop Bits: [0] Even Parity, 1 Stop Bit *
- 20-00 Feedback 1 Source: [2] Analog Input 54 *
- From Main Settings, 8-53 Start Select: [2] Logic AND (Activates Start command via the fieldbus/serial communication port, AND additionally via one of the digital inputs)
- Selector on the LCP: Auto on
(*Should be set by default)
The configuration of the VFD MODBUS register layout must follow the below:
