Contactor control
Contactor output on siliXcon controllers is power output with pwm capability (low side switch). Usually used for controlling contactors.
All here listed variables are located in folder /common/contactoX. Where X is the contactor number.
Do not connect capacitance load to the contactor, the in-rush current will burn the output.
Parameters
attack [-V / +%]
Voltage value during contactor startup.
- Positive value: Set contactor voltage as percentage from battery voltage.
- Negative value: Set contactor value to exac voltage.
attack = 10; battery voltage = 50V voltage on contactor will be 5V
attack = -10 voltage on contactor will be 10V
hold [-V / +%]
Contactor voltage after startup.
- Positive value: Set contactor voltage as percentage from battery voltage.
- Negative value: Set contactor value to exac voltage.
Value "dimension" is same as
attack
attacktime [ms]
When the contactor is closed, attack value is used during attacktime. After that hold value is used.
opts
Options for the contactors.
This is bitwise parameter.
| Bit | Description |
|---|---|
| 0 | Close on driver init |
| 1 | Open on driver or cmio error |
| 2 | Ramp on start |
retrytim [ms]
When overcurrent occurs, the contactor is opened. After this time, the contactor is closed again automatically. To disable this, set this parameter to 0.
Only present on contactors with overcurrent capability.
States
current [mA]
Actual current on the contactor.
Only present on contactors with current measurement capability.
Shell commands
cont [contactor number] [cmd]
You can control manualy contactors. This is also for controling douts on AM controler.
If you run the command with only contactor number, you will get contactor duty cycle, or 1,0 for dout.
| cmd | Description |
|---|---|
| 0 | switch off the contactor |
| 1 | switch on the contactor |
If you enable: Close on driver init, this command will not switch the contactor.
