Parameter 24
(70): general purpose flags, range 0 to 511 PROTECTED!
This parameter consists of five individual flags for controlling servo functions Start with a zero and add
the number shown for each of the following selected options:
+1 :
Interpret Parameter 9 as twice entered value.
+2 :
Disable integral while decelerating (see Parameter 17)
+4 :
Disable integral when brake is engaged (see Parameter 17)
+8 :
Protection of parameters enabled (see Parameter 30)
+16 :
Serial interface disabled
+32 :
Start-up HAAS message disabled
+64 :
Elapsed time display allowed
+128 : Disable Z channel encoder test
+256 : NC overheat and pressure sensor
Parameter 25
(71): brake release time, range 0 to 19 PROTECTED!
If this parameter is zero, the brake is not activated (i.e., always engaged); otherwise this is the delay time
to release the air before the motor is started in motion. It is in units of 1/10 second. A 5 will thus delay
for 5/10 second.
Parameter 26
: RS-232 speed, range 0 to 8
This parameter is always set to 5, a data rate of 4800.
Parameter 27
(73): automatic home control, range 0 to 255 (0 to 512) PROTECTED!
All HAAS Indexers use a home switch used in conjunction with the Z pulse on the motor encoder (one for
each revolution of the motor) for repeatability. The home switch consists of a magnet (Haas PN 69-18101)
and proximity switch (Haas PN 36-3002), which is of the magnetically sensitive transistor type. When the
control is shut down and restarted, it will give a no home display, requiring the user to press the zero
return button. The motor then operates slowly in a clockwise direction (as viewed from the platter of a
rotary table) until the proximity switch is magnetically tripped and then backs up to the first Z pulse. (See
parameter code options in parameter section for actual options.) Note: to reverse direction when seeking a
home switch (if it currently moves away from the home switch during the home sequence), add 256 to the
value in parameter 27.
This parameter is used to customize the home control function of servo.
0:
no automatic home functions available (no home switch)
1:
only table zero position switch available
2:
only Z channel home available
3:
home on both Z channel and table zero switch
+4:
home if inverted Z (determined by encoder used)
+8:
home to zero position in negative direction
+16:
home to zero position in positive direction
+24:
home to zero position in shortest direction
+32:
auto servo on at power on
+64:
auto search for home at power on (have auto servo on at power up selected)
+128: for inverted HOME switch (determined by home switch used)
+256: search for home in positive direction
Parameter 28
(74): encoder steps per motor revolution, 0 to 10000 (0 to 99999) PROTECTED!
This parameter is used with the Z channel option to check the encoder accuracy. If Parameter 27 is 2 or
3, this parameter is used to check that the correct number of encoder steps are received per revolution.
Only two numbers are used here:
32768
for all brushless motors (8192 line encoder x quadrature)
8000
for all brush motors (2000 line encoder x quadrature)
