P0580 – Configuration “Fire Mode”
Adjustable
Range:
0 = Disabled (“Fire Mode” inactive)
1 = Enabled (keeps speed reference/PID setpoint)
2 = Enabled (set speed reference to maximum [P0134])
3 = Enabled (set PID setpoint to the value programmed in P0581)
4 = Enabled (general disable, motor will coast to stop)
Factory
Setting:
0
Properties: cfg
Access groups
via HMI:
HVAC
Description:
This parameter defines how the Fire Mode functionality will work in the CFW501 frequency inverter.
Table 18.12: Options for the parameter P0580
P0580 Description
0 Fire Mode function is inactive.
1 Fire Mode function is active. When the DIx set to Fire Mode is opened (0 V), “A0211” will be shown on the HMI but the
Speed Reference or PID setpoint will not change. The motor will spin according to the Speed Reference or Reference
defined by the PID.
2 Fire Mode function is active. When the DIx set to Fire Mode is opened (0 V), “A0211” will be shown on the HMI and the
Speed Reference will be set automatically to maximum (P0134) value. The motor will accelerate to this new reference.
3 Fire Mode function is active. When the DIx set to Fire Mode is opened (0 V), “A211” will be shown on the HMI and the
PID setpoint will be set automatically to the P0581 value. The motor will spin according to the reference defined by the
PID for this new Setpoint.
4 Fire Mode function is active. When the DIx set to Fire Mode is opened (0 V), “A211” will be shown on the HMI and the
pulses in the output will be disabled. Motor will coast to stop.
P0581 – Fire Mode PID Setpoint
Adjustable
Range:
-32768 to 32767 Factory
Setting:
0
Properties:
Access groups
via HMI:
HVAC
Description:
It defines the setpoint to be used by PID when the “Fire Mode” is enabled and P0580 = 3. The indication of
engineering unit and decimal point position of this parameter on the main display main is defined by parameters
P0510 and P0511.
