Delta DVP-20PM

3 Devices
3.10 Special Auxiliary Relays and Special Data Registers
Special auxiliary relays (special M devices) and special data registers (special D devices) are shown in the
tables below. Some device numbers in the tables are marked with *. Users can refer to section 3.11 for
more information. If the attribute of a device is “R”, the users can only read data from the device. If the
attribute of a device is “R/W”, the users can read data from the device, and write data into the device. In
addition, “-” indicates that the state of a special auxiliary relay is unchanged, or the value in a special data
register is unchanged. “#” indicates that a special auxiliary relay or a special data register in a DVP-20PM
series motion controller is set according to the state of the DVP-20PM series motion controller. The users
can read a setting value, and refer to the manual for more information.

M1000*
If the motion controller runs, M1000 will be a
normally-open contact (Form A contact). When the
motion controller runs, M1000 is ON.
○ ○ Off On Off R No Off 3-30
M1001*
If the motion controller runs, M1001 will be a
normally-closed contact (Form B contact). When
the motion controller runs, M1001 is OFF.
○ ○ On Off On R No On 3-30
M1002*
A positive-going pulse is generated at the time
when the motion controller runs. The width of the
pulse is equal to the scan cycle.
○ ○ Off On Off R No Off 3-30
M1003*
A negative-going pulse is generated at the time
when the motion controller runs. The width of the
pulse is equal to the scan cycle.
○ ○ On Off On R No On 3-30
M1008 The watchdog timer is ON. ○ ○ Off Off - R No Off -
M1009 The low voltage signal has ever occurred. ○ ○ Off - - R No Off -
M1011
10 millisecond clock pulse (The pulse is ON for 5
milliseconds, and is OFF for 5 milliseconds.)
○ ○ Off - - R No Off -
M1012
100 millisecond clock pulse (The pulse is ON for 50
milliseconds, and OFF for 50 milliseconds.)
○ ○ Off - - R No Off -
M1013
1 second clock pulse (The pulse is ON for 0.5
seconds, and OFF for 0.5 seconds.)
○ ○ Off - - R No Off -
M1014
1 minute clock pulse (The pulse is ON for 30
seconds, and OFF for 30 seconds.)
○ ○ Off - - R No Off -
M1025
Incorrect request for communication (If a PC or an
HMI is connected to a DVP-20PM series motion
controller, and the DVP-20PM series motion
controller receives illegal request for
communication during data transmission, M1025
will be set to ON, and an error code will be stored in
D1025.)
○ ○ Off Off - R No Off -
M1026 Selecting a RAMP mode ○ ○ Off - - R/W No Off
M1029
The sending of pulses through CH0 (Y0, Y1) is
complete.
○ ○ Off - - R No Off
M1031 All the non-latching devices are cleared. ○ ○ Off - - R/W No Off -
M1032 All the latching devices are cleared. ○ ○ Off - - R/W No Off -
M1033
Data is retained when the DVP-20PM series motion
controller does not run.
○ ○ Off - - R/W No Off -
M1034 All the outputs are disabled. ○ ○ Off - - R/W No Off -
M1035 Using STOP0/START0 as external I/O terminals. ○ ○ Off Off Off R/W No Off -
