3 Devices
3.4 Auxiliary Relays
Auxiliary relay (M): Auxiliary relay numbers are decimal numbers.
General auxiliary relay
M0~M499 (500 general auxiliary relays)
Users can change M0~M499 to latching devices by setting
parameters.
Latching auxiliary relay
M500~M999 and M3000~M4095 (1,596 latching auxiliary
relays)
Users can change M0~M499 to non-latching devices by
setting parameters.
Auxiliary relay
(M)
Special auxiliary relay
M1000~M2999 (2,000 special auxiliary relays)
Some of them are latching devices.

relays in

Functions of auxiliary relays:
An M device has an output coil and a Form A contact/Form B contact. There is no limitation on the number
of times an M device can be used in a program. Users can combine control loops by means of M devices,
but can not drive external loads by means of M devices. There are three types of auxiliary relays.
1. General auxiliary relay: If a power cut occurs when a DVP-20PM series motion controller runs, the
general auxiliary relays in the DVP-20PM series motion controller will be
reset to OFF. When the supply of electricity is restored, the general
auxiliary relays are still OFF.
2. Latching auxiliary relay: If a power cut occurs when a DVP-20PM series motion controller runs, the
latching auxiliary relays will remain in their last states. When the supply of
electricity is restored, the latching auxiliary relays remain unchanged.
3. Special auxiliary relay: Every auxiliary relay has its own specific function. Please do not use the
auxiliary relays which are not defined. Users can refer to section 3.10 for
more information about special auxiliary relays and special data registers,
and refer to section 3.11 for more information about the functions of
special auxiliary relays and functions of special data registers.
3.5 Stepping Relays
Stepping relay (S): Stepping relay numbers are decimal numbers.
General
stepping relay
S0~S499 (490 general stepping relays)
Users can change S0~S499 to latching devices by setting
parameters.
Stepping relay

Latching
stepping relay
S500~S1023 (524 latching stepping relays)
Users can change S500~S1023 to non-latching devices by setting
parameters.

stepping
relays in
total
Functions of stepping relays:
There are 1024 stepping relays (S0~S1023). An S device has an output coil and a Form A contact/Form B
contact. There is no limitation on the number of times an S device can be used in a program. Users can not
drive external loads by means of S devices. An S device can be used as a general auxiliary relay.
3.6 Timers
Timer (T): Timer numbers are decimal numbers.
Timer
(T)
10 ms
General timer
T0~T255 (256 general timers)
Users can change T0~T255 to latching devices by setting parameters.
Functions of timers:
10 milliseconds are a unit of measurement for time. A timer counts upwards for measuring time which
elapses. If the present value of a timer is equal to the value set, the output coil of the timer will be ON. The
value set can be a decimal value preceded by K, or the value in a data register.
