WARNING

The VM24 I/O Module sends and receives signals for controlling your system's
electrical and mechanical components. Therefore, you should test your system for
safety under all potential conditions. Failure to do so can result in damage to
equipment and/or serious injury to personnel.

2 VM24 I/O Module

Overview — VM24

The VM24 external I/O modules act as an interface for the general-purpose
programmable inputs and outputs of all the 6000 Series servo and
microstepping products. The VM24 module consists of a base board and one
to three SIM (single in-line module) style boards that can be inserted to
provide the user with a scaleable solution for their input and output needs.

• The outputs are enhanced by an undervoltage lockout circuit and a
thermal shutdown protection circuit. These outputs operate over 5VDC
to 24VDC, will sink 50 mA to 0.4VDC or 300mA to 2.5VDC, and
will source 50 mA to a voltage level of Vo – 2VDC (user-supplied

voltage level Vo minus 2 volts, e.g. for Vo=24V, output is 22V) or
300 mA to a voltage level of Vo – 2.5VDC (user-supplied voltage
level Vo minus 2.5 volts, e.g. for Vo=24V, output is 21.5V).

• The inputs are enhanced by decompression, hysteresis, high-frequency
filtering, and overvoltage clamping. These inputs, capable of operating
in sinking or sourcing mode, have a range from 5VDC to 24VDC. The
switching level for inputs is based on the user-supplied voltage Vi, such

that OFF ≤1/3 (Vi) and ON ≥ 2/3 (Vi), with hysteresis of 1/3(Vi).
(For example, with Vi of 24VDC, OFF ≤ 8VDC and ON ≥ 16VDC,
with 8VDC of hysteresis.) Jumpers are used to configure the inputs as

sinking or sourcing. Each of the three SIM sockets has its own
corresponding jumper, allowing each input SIM to be independently
configured.

The VM24 module accepts a 50-pin ribbon cable from the 6000 Series
product and provides screw terminal connections for easier interface with the
user's application. The 24 I/O signals to/from the 50-pin DIN connector and
the 50-pin screw terminal are interrupted by three SIM sockets (each SIM
interrupts an 8-bit group of signals).

Optical isolation is inherited from the 6000 product, except for OEM
products. (I/O ground is isolated from microprocessor ground, but inputs and
outputs are not isolated from each other.)

Specification Summary

Parameter Specification

Power Requirements

Vo ........................ User-supplied voltage that drives output circuitry.

Vo does not affect input circuitry, so it is not

necessary for the VM24-IN.

Vo Range................ 5-24VDC

Vo Current .............. 144mA, plus the sum of the load currents outputs

that are in sourcing mode.

Vi.......................... User-supplied voltage that drives input circuitry &

determines switching levels for inputs. Does not
affect output circuitry, so it is not necessary for
the VM24-OUT.

Vi Range ................ 5-24VDC

Vi Current............... 1.5mA per volt of V

(e.g., 15mA for Vi=10V)

+5V....................... Supplied by the 6000 Series Controller/Indexer

through the 50-pin ribbon cable to connector J4.
The VM24 draws 0.25mA per active output and

0.5mA per active input. Also provides the
+5V output power available through the
VM24 screw terminal block J5.

Inputs

Switching levels....... LOW ≤ 1/3 (Vi )

HIGH ≥ 2/3 (Vi)

Voltage Range.......... 0-24V. Voltage of input signals should not

exceed voltage level of Vi. (Input circuitry of
VM24 has diodes to protect against voltages that

exceed Vi, but performance may degrade.)

Sinking Current:....... Connect jumper for desired socket to position 3

(default)

Sourcing Current: ..... Connect jumper for desired socket to position 1

i

4 VM24 I/O Module

Impedance................ 6 kΩ, minimum. Requires input current

(sourcing or sinking) of 0.111mA per volt of
user-supplied voltage Vi. (e.g., 1.11mA for

Vi=10V).

Status: .................... Check with the TIN or INFNC command.

Active Level: ........... Set by 6000 Series Controller/Indexer. Default is

active low, but can be changed to active high with
the INLVL command.

Input frequency......... 50 kHz (the maximum frequency is limited

practically to 500 Hz by the 2 ms update rate of
the 6000 Series.

Outputs

Voltage................... Sourcing Current

Output voltage level is 2 volts less than the user­supplied voltage Vo when sourcing up to 50mA.

(Vo – 2 VDC for 50 mA
e.g. for Vo=24V, output is at 22V)

Output voltage level is 2.5 volts less than the
user-supplied voltage Vo when sourcing up to

50mA.
(Vo – 2.5VDC for 300 mA

e.g. for Vo=24V, output is at 21.5V)

Sinking Current

Output voltage level is less than or equal to

0.4VDC when sinking up to 50mA.
(≤ 0.4 VDC for 50 mA)

Output voltage level is less than or equal to

2.5VDC when sinking up to 300mA.
(≤ 2.5 VDC for 300 mA)

Current ................... 300mA maximum per output, continuous duty at

50°C ambient temperature

Status:.................... Check with the TOUT or OUTFNC command.

Active Level: ........... Default is active low, but can be changed to active

high with the OUTLVL command.

Rise Time ............... Load dependent; typically 40ns per 1000 pF

Fall Time ................ Load dependent; typically 40ns per 1000 pF
