: Disable safety C-L
Adjustment range : 0 or 1.
Factory setting
: 0.
Mnemonic :
C1-3.
b26 = 0 : the security operates if the reference current is
less than 3mA.
b26 = 1 : the security does not operate.
: Specific braking
Adjustment range : 0 or 1.
Factory setting
: 0.
Mnemonic :
C1-2.
b27 = 0 : standard deceleration. When there is a sharp
decrease in the reference, if the inertia is significant and
is tending to increase the D.C. bus voltage, deceleration
is interrupted to avoid an overvoltage fault OU (operation
identical to a stop with b2 = b7 = 0).
b27 = 1 : specific deceleration. When there is a sharp
decrease in the reference, if the inertia is significant and
is tending to increase the D.C. bus voltage, the inverter
tries to follow the ramp even though this may cause
an overvoltage fault OU (operation identical to a stop
with b2 = b7 = 1).
: Enable P.I. control loop
Adjustment range : 0 or 1.
Factory setting
: 0.
Mnemonic :
PI.
b28 = 0 : the P.I. loop is disabled, the frequency inverter
is controlled by the frequency (or " torque ") reference in
the usual way.
b28 = 1 : the P.I. loop is enabled, the frequency inverter
can regulate an external measurement (flow rate,
pressure, temperature, etc).
The proportional gain is set via P25.
The integral gain constant is set via P26.
The reference of the characteristic to be regulated is
input terminal C2. The feedback sensor is a current
signal at terminal C5 (see commissioning, section 4.4).
: Acceleration ramps for preset speeds
1 to 7
Adjustment range : 0.2 to 600s.
Factory setting
: 5.0s.
Mnemonic :
A1 to A7.
In increments of 0.1s.
With b21 = 1, each preset speed, P20 to P26, has an
associated acceleration ramp, set via P30 to P36
respectively.
Eg. : the acceleration ramp for reaching preset speed
P22 is set via P32.
See the diagram of parameters P40 to P46.
: Acceleration ramp for jogging
Adjustment range : 0.2s to 600s.
Factory setting
: 0.2s.
Mnemonic :
AJ.
In increments of 0.1s.
The jogging operation function always has an associated
acceleration ramp, set via P37.
: Deceleration ramps for preset speeds
1 to 7
Adjustment range : 0.2s to 600s.
Factory settings : 10s.
Mnemonic :
D1 to D7.
In increments of 0.1s.
With b21 = 1, each preset speed, P20 to P26, has an
associated deceleration ramp, set via P40 to P46
respectively.
Eg. : the deceleration ramp for reaching preset speed
P26 is set via P46.
Caution
The change from a preset speed to the analogue
reference (potentiometer) is carried out according to
standard ramps P2 and P3.
Eg. : Calculation of P43 to obtain a time t between P22
and P23.
Where t is in s and ULF, P22, P23, P43 in Hz.
: Deceleration ramp for jogging
Adjustment range : 0.2s to 600s.
Factory setting
: 0.2s.
Mnemonic :
DJ.
In increments of 0.1s.
The jogging operation function always has an associated
deceleration ramp, set via P47.
: Number of automatic resets
Adjustment range : 0 to 5.
Factory setting
: 0.
Mnemonic :
RN.
In increments of 1.
The inverter resets automatically after a trip. If the run
command is maintained, the inverter can then drive the
motor with no external intervention .
P50 sets the number of resets which the inverter will
perform. If P50 = 0, the function is disabled.
Each time an automatic reset is performed (P50
≠
0),
the number of resets still available is displayed
together with the trip code.
