Chapter 4 - Configuring Your System
This option is used to select acceleration (and deceleration) units.All acceleration
and deceleration values specified in the system will be expressed in these units.
You can specify acceleration as a rate,or in time-to-accelerate to full speed.
1.
Use
ß
and
à
keys to select an axis.
2. Use the
áâ
and ENTER keys to select acceleration units from the list:
• sec (time to reach top speed)
• (DIST units)/sec
2
• rps 2 (motor Revolutions Per Sec 2 )
This parameter limits the top speed of your motor. Depending on the application,
you may want to limit the speed of your control to prevent accidental damage to
your mechanics. For example,in a leadscrew driven system, exceeding the “critical
speed”will damage the leadscrew or ballscrew.
1.
Use
ß
and
à
keys to select an axis.
2. Use the numeric k eys to set the maximum velocity in VEL units.

Configuring Acceleration Maximum [AM]
Default: 0.002 (acceleration units)
Range:
0.002 - 99999999 (acceleration units)
Acceleration maximum sets a maximum acceleration and deceleration limit for pro-
grammed move profiles in the cur rent acceleration units.Programmed accelera-
tions and decelerations for moves will be limited by this parameter (analogous to
VMAX for velocity).Regardless of acceleration units,the absolute maximum accel-
eration is 0.002 seconds.
1. Use the
ß
and
à
keys to select an axis.
2. Use numeric keys to enter a new acceleration maximum in the same units
selected in the SETUP > MECH > ACCEL menu and press ENTER then ESC to
