Cascade Controller Option
VLT Drive and Cascade
Controller Setup
Quick Menu 005 Par. 105 Motor current
(MOTOR CURRENT)
Value:
0.01 - Drive rating
✭
Depends on motor
Function:
The rated motor current in amps forms part of the
VLT frequency converter calculations for torque
and motor thermal protection.
Description of choice:
Set a value that equals the nameplate data
on the motor.
NB!:
It is important to enter the correct value, since
this forms part of the VVC
+
control feature.
Quick Menu 006 Par. 106 Rated motor speed
(MOTOR NOM. SPEED)
Value:
100 - 60000 rpm
✭
Depends on parameter 102,
Motor power
Function:
This is where the value is set that corresponds to the
rated motor speed found on the nameplate data.
Description of choice:
Set a value that corresponds to the motor
nameplate data.
NB!:
It is important to set the correct value, since
this forms part of the VVC
+
control feature.
The maximum value equals frequency x 60. Frequency
is set in parameter 104,
Motor frequency
.
Quick Menu 007 Par. 201 Output frequency
low limit
(MIN. FREQUENCY)
Value:
0.0 - Parameter 202 setting
✭
0.0 HZ
Function:
This is where to select the minimum output frequency.
The drive will be unable to run continuously
below this value in any mode.
Description of choice:
Set a value from 0.0 Hz to the
Output frequency high
limit
set in Quick Menu item 008 (parameter 202).
Quick Menu 008 Par. 202 Output frequency
high limit
(MAX. FREQUENCY)
Value:
Para 201 setting - Para 200 limit
✭
60 Hz
Function:
In this parameter, a maximum output frequency can
be selected that corresponds with the maximum motor
speed. The drive will not be able to run continuously
at an output frequency above this value in any mode.
NB!:
Set the output frequency high limit to 60 Hz
for US applications. The output frequency
of the VLT frequency converter can never
assume a value higher than 1/10 of the switching
frequency (parameter 407,
Switching frequency
).
Description of choice:
Enter a value between the low frequency limit, set
in Quick Menu item 07 (parameter 201), and the
frequency range limit, set in parameter 200.
Quick Menu 009 Par. 206 Ramp-up time
(RAMP UP TIME)
Value:
1 - 3600 sec.
✭
Depends on unit
Function:
The ramp-up time is the acceleration time from 0 Hz
to the rated motor frequency (parameter 104,
Motor
frequency
). It is assumed that the output current
does not reach the current limit (set in parameter
215,
Current limit
). This determines the maximum
acceleration rate for all modes of operation.
