Process unit max value
Value shown on V4.5 when source variable is at its
maximum. Proportionality is kept if source
overtakes the maximum.
Application setting (Control
panel: Menu PAR->P15)
Pre heat function
0
= not used
1
= pre heat current always active in stop
state
2
= pre heat controlled by digital input
defined in P5.17
3
= pre heat active when the drive's heat-
sink temperature is below the limit in
P15.3
4
= pre heat active when the external tem-
perature measurements defined in P15.4
are below the limit in P15.5 (option board
HVFDOPTTMP needed)
Pre heat current
Value of DC current to the motor.
Heatsink temperature limit
Considered when P15.1= 3.
Pre heat current is active when the heatsink
temperature is below this value.
External temperature selection
Bit wise selection of temperature inputs.
B0
= Temperature input 1
B1
= Temperature input 2
B2
= Temperature input 3
NOTE: HVFDOPTTMP parameters (in System
menu) for setting of the sensor type must
be configured accordingly.
External temperature limit
Considered when P15.1= 4.
Pre heat current is active when the external
temperature is below this value.
If more than one temperature input is configured
in P15.4, the maximum measurement will be
considered.
