Process unit source selection
Monitor V4.5 can show a process value, proportional to a variable measured
by the drive. Source variables are:
0
= PID feedback value (max: 100%)
1
= Output frequency (max: fmax)
2
= Motor speed (max: nmax)
3
= Motor torque (max: Tnom)
4
= Motor power (max: Pnom)
5
=Motor current (max: Inom)
Process unit decimal digits
Number of decimals shown on monitor V4.5.
Process unit min value
Value shown on V4.5 when source variable is at its minimum. Proportionality
is kept if source overtakes the minimum.
Process unit max value
Value shown on V4.5 when source variable is at its maximum. Proportionali-
ty is kept if source overtakes the maximum.

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 temperature measurements defined in
P15.4 are below the limit in P15.5 (option board OPTBH 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:
OPTBH parameters (in System menu) for setting of the sensor
type must be configured accordingly.
