Appendix A: IDC Actuator Ratios
Configuring inch & mm Units on Smart Drives Used With IDC Actuators
One of the first steps in setting up an IDC Smart Drive with an IDC linear actuator
is to configure the distance, velocity, and acceleration to use meaningful units,
probably
inches or millimeter s .This is done via the RATIO (GR) command.The
RATIO is the number of motor r evs per distance unit .The Distance Unit used is
selected via the SETUP/MECH menu from the keypad or Application De veloper .
Example:GR5:1 means 5 motor revs per 1 distance unit.Several other examples are
available in the
Configuring Your System chapter of your Smart Drive manual.
The RATIO is also used to scale the velocity and acceleration numbers when user
units/sec or units/sec
2
have been selected from the velocity or acceleration menus.
Until now, since each actuator has its own “revs per inch” ratio,data from the
model number had to be interpreted and then a ratio calculated.The following
pages reduce that procedure to looking up the inch or mm ratio from a table
sorted by actuator model number. Instructions are also included to calculate a ratio
for other distance units.Increased positional accuracy is often achieved when
using these values,because some ratios aren’t exact (“3.5:1”is really 50:14,or
3.571428...).
Methods For Configuring Ratio
There are three methods for entering the ratio information.The keypad is probably
the quickest method,if your system includes that option.
1.
Smart Drive Keypad [EDIT-SETUP-MECH-RATIO menu]
2. Application Developer [Setup,Axis Menu]
3. Direct RS-232C connection [GR Command]
