PARAMETERS
Parameter 29
(75): back-EMF compensation, range 0 to 999 (not used for brushless software) PROTECTED!
This parameter is used to control the adjustment of loop gain in response to motor generated back-EMF.
It is set to 10 times the back EMF per 1000 RPM. Thus if the motor has 24.6 volts per KRPM this
parameter is set to 246.
Parameter 30
: protection, range 0 to 65535
This parameter is used to protect some of the other parameters. Every time the controller is turned on, this
parameter will have a new, random, value. If protection is selected (Parameter 24), the protected
parameters cannot be changed until this parameter is set to a different value that is a function of the initial
random value.
Parameter 31
: CNC Relay Hold Time, range 0 to 9
This parameter is used to specify the amount of time the CNC interface relay is held active at the end of
a step. If zero, the relay time is ¼ second. All other values give the time in multiples of 0.1 second.
Parameter 32
(78): delay time for engaging brake, range 0 to 19 PROTECTED!
This parameter is used to set to amount of time delay between the end of a motion and engaging the air
brake. It is a unit of 1/10 seconds. A 4 will thus delay for 4/10 second.
Parameter 33
: X-on/X-off Enable, (0 or 1)
This parameter is used to enable the sending of the X-on and X-off codes via the RS-232 interface. If your
computer needs these, this parameter should be set to 1. Otherwise, only the RTS and CTS lines can be
used to synchronize communication. (See section 2.3 on RS-232 Interface.)
Parameter 34
(80): belt stretch adjustment, range 0 to 99 PROTECTED!
This parameter is used to correct for stretching in a belt if one is used to couple the motor to the load being
moved. It is a count of the number of steps of motion that are added to the motor position while it is in
moving. It is always applied in the same direction as the motion. Thus, when motion stops, the motor will
snap backwards to take the load off the belt.
Parameter 35
(81): dead zone compensation, range 0 to 19 PROTECTED!
This parameter is used to compensate for the dead zone in the driver electronics. It is normally set to 0 or
1.
Parameter 36
(82): maximum speed, range 0 to 25000 PROTECTED!
This parameter defines the maximum feed rate. The value used is (Par 36)*10 in encoder steps/second.
The highest speed is thus 250000 steps per second. It must be less than or equal to Parameter 18. If
this parameter exceeds Parameter 19, only the smaller number is used. See Parameter 19 also.
Parameter 37
(83): encoder test window size, range 0 to 999
This parameter defines the tolerance window for the Z channel encoder test. This much error is allowed
in the difference between the actual encoder position and the ideal value when the Z channel is
encountered.
Parameter 38 (Dual Control Brush Type Only)
secondary axis, range 0 to 1
This parameter normally states whether or not there is a secondary axis, and is set to one if there is.
Normally, it is set to 1 for the tilting rotary table.
The following parameters are for brushless motors:
Parameter 38
(84): KDD (0 to 9999)
Servo loop second differential gain.
Parameter 39
(85): phase offset (0 to 9)
Offset of encoder Z-pulse to zero degree of phasing.
