Mode
Max Acceleration
[ 1 : 127 ]
Determines the S-curve acceleration when using RS232
command mode. Also controls the response time of the
first order low pass filter in speed and torque servo control
(soft start).
*Max Acceleration is automatically reset to 12 after power
OFF

Speed
Torque
Max Speed
[ 1 : 127 ]
Determine the S-curve max speed when using RS232
mode to make point to point motion linear/circular.
*Max Speed is automatically reset to 24 after power OFF

Driver ID
[ 1 : 126 ]
Every drive has a unique ID number, which can be
assigned. Parameter only settable when
RS485/232 Net
box not set (checked), and there is only one Drive con
-
nected through the RS232 port. The default ID number
for every Drive is 0. This ID number can be used for the
network connection of RS485 or for drive unit identifica
-
tion purposes. When
RS485/232 Net
box is checked and
there are more than one Drive connected to the physical
RS485/232 network, only the setting for the Drive with
the indicated ID number in the DMMDRV ServoSetting
module can be read out or saved.

On Position Range
[ 1 : 127 ]
On position range is a value used for determining whether
the motor has reached the command position. On posi-
tion range is selectable according to user’s requirement.
Suppose the Pset is the commanded position, and Pmotor
is the real motor position, if
|Pset - Pmotor|<=
OnPosRange
it is said motor is ON the commanded position, otherwise
not.
On position range defined as:
OnPosRange
x4/65,536x360(deg) = “On Position” (deg)
Ex. If
OnPosRange
is set to 24, then:
24x4/65536x360=0.53deg
JP4. Pin 6 Phototransistor becomes ON when motor
within 0.53degree of command position.

Gear Num
[ 500 : 16,384 ]
The amount of motor travel with reference to the number
of input pulses is set using the parameter Gear_Num.
The number of reference pulse needed for one complete
motor revolution is calculated as,
One motor revolution = 4xGEAR_NUM
For example, if Gear_Num is set to 4,096, then 16,384
pulses are needed from the host controller for the motor to
rotate one complete revolution.
Position
RS232
Line Num
[ 500 : 4,095 ]
The number of pulse outputs per motor revolution from
JP5 encoder output. Number of pulse output calculated
as:
Pulse output per rev = LINE_NUM * 4
If LINE_NUM = 2,000 then 8,000 pulses will be output per
servo motor revolution. Pulse output active for all servo
modes.
