Parameter 21: RS-232 Interface Axis Select, range 0 to 9
When this parameter is zero, no remote RS-232 functions are available. Must be set to zero when
uploading or downloading programs. When it is 1 to 9, that number is used to define the axis code for this
controller. U is 1, V is 2, W is 3, X is 4, Y is 5, and Z is 6. 7 through 9 are other ASCII character codes.
Parameter 22: Maximum Allowed Servo Loop Error, range 0 to 4000 (0 to 99999) PROTECTED!
When this parameter is zero, no maximum error limit test is applied to the servo. When it is non-zero, that
number is the maximum allowed error before the servo loop is turned off and an alarm generated. This auto
shut-off results in a display of:
Parameter 23: Fuse Level in %, range 0 to 100 PROTECTED!
This parameter is used to define a fuse level for the servo control loop. The value is a percentage of
maximum power level available to the controller. It has an exponential time constant of about 30 seconds.
If exactly the set level is output by the driver continuously, the servo will shut off after 30 seconds. Twice
the set level will shut the servo off in about 15 seconds. This parameter is factory set and is usually set
from 25% to 40%, depending on the product. This auto shut-off results in a display of: Hi LoAd.
Warning! Changes from HAAS recommended values will damage the motor.
Parameter 24: General Purpose Flags, range 0 to 1023 (0 to 4095) PROTECTED!
This parameter consists of 12 individual flags for controlling servo functions.
+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:
Lower lag in compensation
+128:
Disable Z channel encoder test
+256:
Normally closed over temp sensor
+512:
Disable cable test
+1024: Disable rotary scale encodercable test (HRT210SC only)
+2048: Disable rotary scale encoder Z testHRT210SC only
Parameter 25: 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 used to select data rates on the RS-232 interface. The parameter values and rates are:
