If a new

Go

or

Relative Move

command is given to the slave axis which removes the

Sync bit used in the

MODE

word, then that slave will perform the new move, and the

master will continue its move.

If a new

Go

or

Relative Move

command is given to the master axis which removes

the Sync bit used in the

MODE

word, then the master will perform the new move, but

the slave axis will stop.

If a new

Go

or

Relative Move

command is given to the second axis which retains the

Sync bit in the

MODE

word, then the axes will start a new synchronized move from

their current positions.

NOTE: Because a new

Go

or

Relative Move

command will cause the travel distance

ratios to be recalculated, any change in the speeds or travel distances of any of

the axes may result in a speed discontinuity in the new slave axis, although the

position will always be continuous.

It is normally not possible to use DCS120-Win to issue commands to both axes

simultaneously. However, when a command is issued to an axis that has a sync bit set,

the software will automatically issue commands all axes with the Sync bit set. This can

only be done while in

Write mode

. Similarly, if a

Stored Command

is a synchronized

command and is executed, the Stored Command for the other axis will be executed

simultaneously if it has the Sync bit set also.

VC2100 Two Axis Voltage-to-Current Converter

The VC2100 voltage-to-current converter transforms

±

10V signals into current signals

capable of driving hydraulic servo valves or similar loads. It also provides a convenient

way to set the full scale current to match valve requirements, limit maximum current and

set optimum working ranges.

Features

Two channels of voltage-to-current conversion

Full scale range (FSR) output current for each channel is switch-selectable from

±

10mA to

±

100mA in 10mA steps

Dual-color LEDs indicate input polarity and amplitude

Outputs protected against inductive voltage spikes

Compact DIN rail mount

Use with

±

12 to

±

15 volt power supplies
