Danfoss VLT 6000 HVAC Series User Manual

MSB:
Most significant bit.
Used in serial communication.
n
M,N
The rated motor speed (nameplate data).
η
VLT
The efficiency of the frequency converter is defined as
the ratio between the power output and the power in-
put.
On-line/off-line parameters:
On-line parameters are activated immediately after the
data value is changed. Off-line parameters are not ac-
tivated until OK has been entered on the control unit.
PID:
The PID regulator maintains the desired speed (pres-
sure, temperature, etc.) by adjusting the output fre-
quency to match the varying load.
P
M,N
The rated power delivered by the motor (nameplate
data).
Preset ref.
A permanently defined reference, which can be set
from -100% to +100% of the reference range. There
are four preset references, which can be selected via
the digital terminals.
Ref
MAX
The maximum value which the reference signal may
have. Set in parameter 205 Maximum reference,
Ref
MAX
.
Ref
MIN
The smallest value which the reference signal may
have. Set in parameter 204 Minimum reference,
Ref
MIN
.
Setup:
There are four Setups, in which it is possible to save
parameter settings. It is possible to change between
the four parameter Setups and to edit one Setup, while
another Setup is active.
Start-disable command:
A stop command that belongs to group 1 of the control
commands - see this group.
Stop command:
See Control commands.
Thermistor:
A temperature-dependent resistor placed where the
temperature is to be monitored (VLT or motor).
Trip:
A state which occurs in different situations, e.g. if the
frequency converter is subjected to an over-tempera-
ture. A trip can be cancelled by pressing reset or, in
some cases, automatically.
Trip locked:
Trip locked is a state which occurs in different situa-
tions, e.g. if the frequency converter is subject to an
over-temperature. A locked trip can be cancelled by
cutting off mains and restarting the frequency convert-
er.
U
M
The voltage transmitted to the motor.
U
M,N
The rated motor voltage (nameplate data).
U
VLT, MAX
The maximum output voltage.
VT characteristics:
Variable torque characteristics, used for pumps and
fans.
