20.2 - Explanation of parameters in
menu 21
: Motor 2 maximum reference clamp
Adjustment range : 0 to 32000 rpm
Factory setting
: Eur = 1500 rpm
USA = 1800 rpm
This parameter defines the maximum speed in both directions
of rotation.
This parameter is equivalent to
1.06
for motor 1.
• Before setting the maximum reference clamp,
check that the motor and the driven machine can
withstand it.
: Motor 2 minimum reference clamp
Adjustment range : 0 to 32000 rpm
Factory setting
: 0
In unipolar mode, this parameter defines the minimum speed.
WARNING:
This parameter is inactive during jog operation.
This parameter is equivalent to
1.07
for motor 1.
: Motor 2 reference selector
Adjustment range : 0 to 4
Factory setting
: 0
0 (Term. inputs) (SEL): The speed reference is selected
by combining the digital inputs assigned to parameters
1.41
and
1.42
.
1 (Analog 1) (Ana1): The speed reference comes from
analog input 1.
2 (Analog 2) (Ana2): The speed reference comes from
analog input 2.
3 (Preset) (Pr): The speed reference comes from the preset
references.
4 (Keypad) (Pad): No speed reference is taken into account.
This parameter is equivalent to
1.14
for motor 1.
: Motor 2 acceleration rate
Adjustment range : 0 to 600.0 s/1000 rpm
Factory setting
: 3 s/1000 rpm
Sets the time for acceleration from 0 to 1000 rpm.
21.04
=
This parameter is equivalent to
2.11
for motor 1.
: Motor 2 deceleration rate
Adjustment range : 0 to 600.0 s/1000 rpm
Factory setting
: 5.0 s/1000 rpm
Sets the time for deceleration from 1000 rpm to 0.
21.05
=
This parameter is equivalent to
2.21
for motor 1.
: Motor 2 nominal frequency
Adjustment range : 0 to 400.0 Hz
Factory setting
: Eur = 50.0 Hz
USA = 60.0 Hz
This is the point at which motor operation changes from
constant torque to constant power.
During standard operation, it is the frequency indicated on the
motor nameplate.
This parameter is equivalent to
5.06
for motor 1.
: Motor 2 nominal current
Adjustment range : 0 to drive rated current (A)
Factory setting
: Motor rated current corresponding to the
drive rating
This is the value of the motor rated current indicated on the
nameplate. Above this value the motor is overloaded.
This parameter is equivalent to
5.07
for motor 1.
: Motor 2 nominal speed
Adjustment range : 0 to 9999 rpm
Factory setting
: Motor rated speed corresponding
to the drive rating
This is the on-load speed of the motor indicated on the
nameplate.
This parameter is equivalent to
5.08
for motor 1.
