Description
Refer to section 2 in the “VIO Operating Manual”
The VIO-STARTER is an add-on interconnection board for the VIO servo amplifier
that plugs on top of the amplifier. The purpose of this board is the translation of the VIO
solder type pins into screw type terminals thus enabling easy connectivity for evaluation
and low quantity applications.
One to one relationship between board terminals and the pins of the VIO is kept.
Standard Features
Refer to section 2.1 in the “VIO Operating Manual”
q Four LEDs allow convenient diagnostics of the VIO status outputs
q The dedicated digital inputs can be activated by DIP switches
q Scaling resistors are provided for adjusting the current limits and the command
reference
Type designation
VIO-Starter
Pins functions
There is a new terminal strip – J4 with the following functions:
Terminal Function
+VCC Positive supply voltage for the LED’s
VCCRET Return for the LED supply voltage
Current Command Scaling Resistors (R1 & R2)
Refer to section 3.1 in the “VIO Operating Manual”
The user can change the default scale of the differential input (
±
3.75V) by calculating
and inserting R1 & R2 into the designated solderless terminals. The value of theses
resistors is given by:
R1=R2=5.33*Vcref-20 [K
Ω
]
Vcref is the desired maximum reference voltage.
If for example, the new desired scale is ±10V, all that is required is to change the
default resistors (0 ohms) to 33Kohm.
External Current Limit – Continuous (ECLC)
Refer to section 3.4 in the “VIO Operating Manual”
A solderless terminal is available for Reclc. It is designated as R3.
External Current Limit – Peak (ECLP)
Refer to section 3.5 in the “VIO Operating Manual”
A solderless terminal is available for Reclp. It is designated as R4.
