CLRS Series RS485 Closed Loop Stepper Drive User Manual
DI2=0x29 (means path 1);
(2) The data type of parameter is 32bit, which include high 16bit register and low 16bit register, usually we use low
16bits only, but it needs to take the high 16 bits as beginning when we read/write multiple parameters continuously.
4.3 Modbus & PR Parameters
4.3.1 Basic Parameters
STEPPERONLINE RS485 parameter data type is 32 bits, a parameter contains two registers of high 16 bits and
low 16 bits, only the lower 16 bits are used in practice. However, when reading or writing multiple parameters in
succession, the high 16 bits of the parameter need to be used as the start, usually 00.
Value “0” for open loop;
Value “2” for closed loop;
Value “1” is reserved.
Allowed max position
following error
It’s used to set the allowed max pulse count
of position errors.
Software forced enable has a higher priority
than IO enable, and when this value is 0, the
enable status of the drive only depends on
the IO signal. When this value is 1, the motor
is enabled regardless of the IO signal status.
Increase this value will reduce position
following error, but could result in motor
vibration
This parameter is used for tuning Velocity
loop proportional gain.
Increase the value can increase velocity
stiffness
To configure the time for internal command
filtering
Velocity switching point:
open loop to closed loop
Usually keep the default value.
Only change it when it causes motor
vibration at this mode switching velocity
point.
Velocity switching point:
closed loop to open loop
Usually keep the default value.
Delay time of open loop
to closed loop
Usually keep the default value.
Delay time of closed loop
to open loop
Usually keep the default value.
Default is normal-open (N.O) type, it can be
set to normal-closed (N.C) type by setting
the corresponding port +0x80
SI1 is enable(default), N.C type input.
0: invalid; 7: alarm clearing;
8: enable (also can be set by 0x00F);
0x20: Trigger command (CTRG);
0x21: Trigger homing;
0x22: EMG (quick stop);
0x23: JOG+;
0x24: JOG-;
0x25: POT (positive limit);
