FIRE MODE PID APPLICATION

1. INTRODUCTION

The application is functionally the same as the PID application (ASFIFF05) with the addition of
the fire mode features. Fire mode is selected via a digital input (programmable). The
frequency is set according to logic in Figure 1. When fire mode is active, a fire mode warning
(A81) is brought up on the display. When running in fire mode, the converter is programmed
to enable the user to run the converter until either the digital input is removed or the
converter is damaged.

Additional features when fire mode is selected:

• Run enable always active

• Run request always active

• Direction change not allowed

• Fault signal on digital outputs inactive

• Possible to connect fire mode signal to digital outputs

• Software generated faults are changed to warnings (Drive does not stop)

• Forced reset of hardware system faults (Delay time is set with parameter

P2.10.5)

• Fire Mode frequency reference can be PID-output or two selectable preset

speeds

• Monitor value V1.22 is stored if fire mode have been used (Counter)

2. FIRE MODE PID APPLICATION – PARAMETER LISTS

On the next pages you will find the lists of parameters within the respective parameter
groups. The parameter descriptions are given on pages 9.

Column explanations:

Code = Location indication on the keypad; Shows the operator the present parameter

number
Parameter = Name of parameter
Min = Minimum value of parameter
Max = Maximum value of parameter
Unit = Unit of parameter value; Given if available
Default = Value preset by factory
Cust = Customer’s own setting
ID = ID number of the parameter (used with PC tools)
= On parameter code: Parameter value can only be changed after the frequency

converter has been stopped.
