12.46 : Brake delay
Adjustment range : 0.00 to 25.00 s
Factory setting : 0.30 s
Format: 16 bits
: This time delay is triggered when all the conditions for
brake release have been met. It allows enough time to
establish an adequate level of flux in the motor and to ensure
that the slip compensation function has become fully active.
When this time delay has elapsed, brake control is enabled
( 12.40 = Enabled (1)).
During the whole of this time delay, the ramp applied to the
reference is held constant ( 02.03 = Yes (1)).
: This time delay is used to delay the brake apply command
in relation to the passage below the minimum speed
threshold ( 12.45 ). It is useful for avoiding repeated oscillation
of the brake when it is being applied around zero speed.
12.47
: Post-brake release delay
Adjustment range : 0.00 to 25.00 s
Factory setting : 1.00 s
Format: 16 bits
This time delay is triggered when brake control is enabled. It is
used to allow time for the brake to release before unlocking the
ramp ( 02.03 = No).
12.48 : Brake apply delay ( )
Adjustment range : 0.00 to 25.00 s
Factory setting : 1.00 s
Format: 16 bits
This time delay is used to maintain the torque at standstill while
the brake is applied. When this time delay has elapsed, the
drive output is deactivated.
12.49 and 12.50 : Not used
12.51
: Forced brake release
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Disabled (0)
Format: 8 bits
When the drive output is active ( 10.02 = Yes (1)), the brake
control output 12.40 is enabled when the release conditions
determined by the brake control are met. When the drive output
is inactive, the brake control output 12.40 is forced to Enabled
(1) if 12.51 is at Enabled (1).
12.51 can be assigned to a digital input but cannot be
written to.
12.52 to 12.60 : Not used
12.61 : Comparator 3 output
Adjustment range : Disabled (0) or Enabled (1)
Format: 8 bits
Disabled (0):
The input variable is less than or equal to the comparator threshold.
Enabled (1):
The input variable is greater than the comparator threshold.
12.62
: Comparator 3 state before delay
Adjustment range: Disabled (0) or Enabled (1)
Format: 8 bits
Indicates the comparator state before the time delay.
12.63 : Comparator 3 source
Adjustment range : 00.00 to 21.51
Factory setting : 00.00
Format: 16 bits
This parameter defines the variable that is to be compared to
the configured threshold.
The absolute value of the variable is used. Only non-bit
parameters can be programmed as the source.
If an unsuitable parameter is programmed, the input value
equals 0.
12.64
: Comparator 3 threshold
Adjustment range : 0.00 to 60000.00 *
Factory setting : 0.00 *
Format: 32 bits
This parameter is used to set the comparator trip threshold.
The threshold is expressed in the unit (rpm, A, V, etc) of the
relevant value.
12.65
: Comparator 3 hysteresis
Adjustment range : 0.00 to 60000.00 *
Factory setting : 0.00 *
Format: 32 bits
This parameter defines the window within which the comparator
output will not change state.
The output will change to Enabled (1) when the variable
reaches the value of 12.64 + 12.65 /2. The output will change
to Disabled (0) when the variable goes below the value of
12.64 - 12.65 /2.
12.66 : Comparator 3 level type
Adjustment range : Over level (0), Under level (1),
Masked under level (2)
Factory setting : Over level (0)
Format: 8 bits
Over level:
Output not inverted.
Under level (1):
Output inverted.
Masked under level (2):
Output inverted with masking on drive enable.
12.67 : Comparator 3 output destination
Adjustment range : 00.00 to 21.51
Factory setting : 00.00
Format: 16 bits
This parameter defines the internal parameter which will be
assigned by the comparator output.
Only bit type parameters can be programmed.
If an unsuitable parameter is programmed, the output is not
sent anywhere.
* The unit is defined by the one used for the source parameter
of the relevant comparator.
