Brake open
When the signal is high the brake is open. The signal becomes inactive when
the brake begins to close.

Brake closed
The signal is 1:active when the brake is closed. The parameter becomes
0:inactive when the brake begins to open.

9.3 Range Control and Display Scaling
Description
The "range control" function gives you an opportunity to monitor a value in data format
I16. When the parameter exceeds a user specified limit you you can have an event
triggered (message, warning or fault).
There are two range controls available. Go to pages 10.1 und 10.2 of the Assistant to set
the control. The following description is based on "range control 1" on page 10.1 of the
Assistant (Figure 9-4).
• Enter the parameter in D60 which you want to monitor. Remember that this parameter
must be in data format I16. If you want to monitor an I32-format parameter you can
scale it to the I16 format with "display scaling." For more information read the following
sections.
• Enter a factor in D61 with which the parameter is to be weighted.
Remember that an entry of 25% corresponds to the factor 1 since a further
multiplication with the factor 4 takes place internally.
• Enter the time constant of the low pass in D62. The low pass smoothes the
progression of the value to be monitored. The result after smoothing is indicated in
D69.
• Specify in D63 how the value indicated in D69 is to be monitored. When D63 is set to
0:range the limits D64 to D67 are evaluated unchanged. When D64 = -50% and D67 =
60% are parameterized the valid working range is between -50% and 60% in this case.
With 1:absolute the limits specified in D64 to D67 are evaluated symmetrically to zero.
When D64 = 50% and D67 = 60% are parameterized the valid working range is
between +50% and +60% or -60% and -50%.
• Enter the limits of the control in D64 to D67.
D64 determines the lowest limit of range control. When the value in D69 passes below
this limit D190 is active and event 60 is triggered.
D65 determines the first lower limit of range control. When this limit is passed below
D191 indicates and signals that the value in D69 is approaching the critical limit D64.
When the value in D69 is between D65 and D66 this is indicated by D192.
D66 determines the first upper limit of range control. When this limit is exceeded D193
indicates and signals that the value in D69 is approaching the critical limit D67.
D67 determines the highest upper limit of range control. When the value in D69
exceeds this limit D194 is active and event 61 is triggered.
• Specify in D68 whether control range is limited to static operation. When 0:inactive is
parameterized range control is not performed during accelerations or disabled drive.
Event signals D190 to D194 are set to 0:inactive. When D68 is parameterized to
1:active range control is performed continuously and D190 to D194 are set
accordingly.
Range control 2 on page 10.2 of the Assistant is parameterized as described here.
