Installing the VM24 3
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 Vominus 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 Vominus 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 Viof 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.
Vodoes not affect input circuitry, so it is not
necessary for the VM24-IN.
VoRange................5-24VDC
VoCurrent..............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.
ViRange ................5-24VDC
ViCurrent...............1.5mA per volt of Vi
(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
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Installing the VM24 5
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 user-
supplied voltage Vowhen 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 Vowhen 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

6 VM24 I/O Module
Undervoltage
Protection.........The under-voltage lockout circuit is meant to
prevent the output driver from sinking or sourcing
unless the user-supplied voltage Vois between
5VDC and 24VDC.
Thermal Shutdown....The thermal shutdown protection is intended to
protect the device from marginal environmental
factors. It must not be considered short circuit
protection. The thermal resistance between the
FET junction and the thermal protection circuit
on the SIM cards is great enough that the rapid
rise in junction temperature caused by a short
circuit will not transfer fast enough to protect the
device from damage.
+5V Output.............Supplied by the 6000 Series Controller/Indexer
through the 50-pin ribbon cable to connector J4.
Accessed on the VM24 through the screw
terminals (J5). Refer to the User/Installation
Guide for the 6000 Series Controller/Indexer
being used for the load limit of its +5V Output.
Subtract any loads being drawn from the +5V
Output at the 6000 Series unit level. The VM24
draws 0.25mA per active output and 0.5mA per
active input from the +5V supply. Use this
information to calculate the load limit available
for the +5V Output on the screw terminal of the
VM24.
NOTE: Outputs are not short-circuit protected.
Environmental
Operating Temp........32 to 122°F (0 to 50°C)
Storage Temp...........-22 to 185°F (-30 to 85°C)
Humidity.................0 to 95% non condensing

Jumper Configuration
The jumpers are used to configure the inputs for the I/O boards as sinking or
sourcing. Each socket has its own corresponding jumper, allowing each
board with inputs to be independently configured for sinking or sourcing.
Sinking Inputs: Position 3 (shown)
Jumps pull-up to Vi (pin 3)
Sourcing Inputs: Position 1
Jumps pull-up to Ground (pin 1)
The default jumper position when shipped from the factory is position 3, as
shown below. The jumper positions only affect inputs on the VM24.
Jumper position does not affect the outputs. Jumper position is irrelevant
for SIM8-OUT boards.

12 VM24 I/O Module
Ribbon Cable Connection
Caution
Remove power to the VM24 before
attaching or removing the cable.
The VM24 is shipped with a 2-foot ribbon cable, with mating connectors.
Connectors are keyed to ensure that they are inserted into mating connectors
correctly. Cable installation for the VM24S, VM24-IN, and VM24-OUT
consists of simply inserting the connector from one end of the cable into the
Programmable I/O connector of the 6000 Series Controller/Indexer, then
inserting the connector at the other end of the cable into connector J4 of the
VM24.
Multi-axis 6000 Series Controller/Indexers have separate input and output
connectors. Therefore, the two multi-axis configurations of the VM24
which offer both inputs and outputs, listed below, require a split cable to
access both of these connectors.
• VM16/8
• VM8/16
The connector that is attached to the portion of the ribbon cable with the red
stripe corresponds to the I/O boards in sockets J2 and J3 — either 16 IN or
16 OUT. This connector should be inserted into its corresponding Input or
Output connector on your 6000 Series Controller/Indexer. See Figures 6 and
7. The connector that is attached to the smaller width of ribbon cable
corresponds to the I/O board in J1 — either the SIM8-IN or SIM8-OUT.
This connector should be inserted into its corresponding Input or Output
connector on your 6000 Series Controller/Indexer.
