Danfoss VLT 6000 series User Manual

VLT
®
6000 HVAC Series
MCM:
Stands for Mille Circular Mil, an American measuring
unit for cable cross-section.
M
SB:
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 input.
O
n-line/off-line parameters:
On-line parameters are activated immediately after the
data value is changed. Off-line parameters are not
activated until OK has been entered on the control unit.
P
ID:
The PID regulator maintains the desired speed
(pressure, temperature, etc.) by adjusting the output
frequency to match the varying load.
P
M,N
The rated power delivered by the motor
(nameplate data).
P
reset 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.
R
ef
MAX
The maximum value which the reference signal
may have. Set in parameter 205 Maximum
reference, Ref
MAX
.
R
ef
MIN
The smallest value which the reference signal may
have. Set in parameter 204 Minimum reference, Ref
MIN
.
S
etup:
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.
S
tart-disable command:
A stop command that belongs to group 1 of the
control commands - see this group.
S
top command:
See Control commands.
T
hermistor:
A temperature-dependent resistor placed where the
temperature is to be monitored (VLT or motor).
T
rip:
A state which occurs in different situations, e.g.
if the frequency converter is subjected to an
over-temperature. A trip can be cancelled by pressing
reset or, in some cases, automatically.
T
rip locked:
Trip locked is a state which occurs in different
situations, 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 converter.
U
M
The voltage transmitted to the motor.
U
M,N
The rated motor voltage (nameplate data).
U
VLT, MAX
The maximum output voltage.
V
T characteristics:
Variable torque characteristics, used for
pumps and fans.
