5.7 Position limit
Modify and/or confirm the position limit during the Motor Setup wizard.
The Position Limit tab in the ServoStudio 2 Limit screen allows you to define position limit. The
following parameters are used to define the position limit mechanism and error tolerance.
Table 5-5
Maximum allowable position error without fault, in the unit of count.
Tolerance window that declares “in position” status.
The digital input number is defined as a signal indicating whether the position
limit has been reached in the positive direction.
The digital input number is defined as a signal indicating whether the position
limit has been reached in the negative direction.
LIMSWITCHPOS
LIMSWITCHNEG
Indicating the status of all positive and negative limit events. Read only.
Enable and disable software position limit and/or transient position limit and/or
homing limit.
Maximum and minimum of the software position limit.
5.8 Motor Direction
When the motion command is positive, the direction of motion can be reversed. For example,
the positive direction of a rotating motor can be clockwise or counterclockwise, depending on the
application requirements.
Test and/or inverse and/or confirm the direction of motion in the Motor Setup wizard.
The following parameters are used ot define the motor direction:
Table 5-6
Motor direction.
DIR can be used to inverse the values of position feedback (PFB), velocity (V) and
current (ICMD), thus reversing the direction of motor movement.
Resolver/encoder phase related to standard commutation table. To inverse the
rotation direction, the value of MPHASE will be increased by 180 degrees.
Define multiple direction and polarity settings. The value of MFBDIR is set by
MOTORSETUP.
Warning!
The values of DIR and MPHASE must be changed simultaneously before the drive is enabled,
otherwise commutation failure (motor runaway) may occur.
5.9 New Motor Wizard
Note: If the drive detects the electronic motor nameplate, the New Motor Wizard cannot be
used during online operation.
