4. ASD Parameter Configuration
Note that whenever any of the parameters documented in this section are 
changed, they must be written to the EEPROM and the control board must be 
initialized (power cycled OFF and back ON again) before the changes will take 
effect. 
 
 
4.1 General Configuration
Program … Communication … Comm configuration … COMM_TYPE 
must be set to 0400h. 
 
There are three possible conditions that can be created upon loss of 
communication or an internal board failure. The drive can be made to coast to 
a stop, ramp to a stop, or take no action. These different actions can be 
selected by changing the masking in the drive as follows: 
 
• 
Coast to stop: Program … Protection … Protection masking … 
MSK_READY1 should have its bits #14 and #15 set to unmask the TL_F1 
and TL_F2 conditions. This is equivalent to adding C000h to whatever 
value the mask is currently set to. 
 
• 
Ramp to stop: Program … Protection … Protection masking … 
MSK_UVA4 should have its bits #12 and #13 set to unmask the TL_F1 and 
TL_F2 conditions. This is equivalent to adding 3000h to whatever value 
the mask is currently set to. 
 
• 
Take no action: Leave the above faults masked off. This option should 
generally be used only if the interface is being used solely for drive 
monitoring. 
 
 
4.2 Receive (Command) Data Configuration
Program … Communication … Comm addressing … Comm read 
addressing … SCAN_R_ADRS must be set to 0. 
 
Program … Communication … Comm addressing … Comm read 
addressing … SCAN_R_SIZE must be set to the number of command items 
the drive is to receive. For example, if only two command words are to be sent 
to the drive, then this value can be set to 2. This will enable the first two 
SCAN_RCVxx_AS parameters, which are numerically indexed via the interface 
as parameters #1 and #2 (refer to section 15.3). Note that there is no penalty 
in setting this parameter to its maximum value (10): any “excess” parameters 
that are not written via the network will have no effect on the drive’s operation.
