Motor Potentiometer Parameters - Honeywell HVAC400x Applications Manual

HVAC400X – APPLICATION MANUAL
P3.3.17 PRESET FREQUENCY 6 (ID 129)
You can use this parameter to set the preset frequency reference when the preset frequencies function is used.
Select the preset frequencies with the digital input signals.
P3.3.18 PRESET FREQUENCY 7 (ID 130)
You can use this parameter to set the preset frequency reference when the preset frequencies function is used.
Select the preset frequencies with the digital input signals. To select a preset frequency between 0 and 7, give
digital inputs to P3.5.1.16 (Preset Frequency Selection 0), P3.5.1.17 (Preset Frequency Selection 1), and/or
P3.5.1.18 (Preset Frequency Selection 2). The different sets of active digital inputs determine the preset frequency.
You can find more data in the table below. The values of the preset frequencies stay automatically between the
minimum and maximum frequencies (P3.3.1 and P3.3.2).
Necessary step
Select the place of reference of I/O in P3.3.3.

P3.3.19 PRESET ALARM FREQUENCY (ID 183)
When the reference signal is cut-off and the alarm action in P3.9.19 is set to 'alarm + preset frequency', then the
drive will run at this alarm preset frequency.

Motor Potentiometer Parameters

Reference P3.3.3 must be set to motor potentiometer and digital inputs P3.5.1.36 and 3.5.1.37 must be selected.
P3.3.20 MOTOR POTENTIOMETER RAMP TIME (ID 331)
You can use this parameter to set the rate of change in the motor potentiometer reference when it is increased or
decreased. The parameter value is entered as Hz/second.
P3.3.21 MOTOR POTENTIOMETER RESET (ID 367)
You can use this parameter to set the logic for the resetting of the frequency reference of the motor potentiometer.
This parameter defines when the reference of the motor potentiometer is set to 0. There are three selections in the
reset function: no reset, reset when the drive stops, or reset when the drive is powered down.
