Modbus RS485 Stepper Drive User Manual
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.
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.
To configure the time for internal command
filtering
Default is normal-open (N.O) type, it can be
set to normal-closed (N.C) type by setting
the corresponding port +0x80
DI1 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);
0x26: NOT (negative limit);
0x27: ORG (home switch);
0x28: ADD0 (path address 0);
0x29: ADD1 (path address 1);
0x2A: ADD2 (path address 2);
0x2B: ADD3 (path address 3);
0x2C: JOG velocity 2
Default is normal-open(N.O) type, it can be
set to normal-closed(N.C) type by setting the
corresponding port +0x80
0: invalid;
0x20: command completed;
0x21: path completed;
0x22: homing completed;
0x23: in-position completed;
0x24: brake output;
0x25: alarm output;
Threshold value of
brake locking velocity
Bit setting:
=1: Yes; =0: No
bit0: over-current ( Cannot be changed)
bit1: over-voltage
bit3: ADC sampling failure
