3-2 Operation
When Set To Bi-directional
When Bi-directional Mode is selected, zero speed occurs at the center
of rotation. Maximum reverse speed occurs in the MIN position and
maximum forward speed occurs in the MAX position.
Acceleration
The Acceleration control allows the user to set the rate of motor
acceleration. It is a 270 degree potentiometer accessible from the front
panel of the ESRS. For tamper avoidance, it is screwdriver operated.
Minimum acceleration occurs in the MIN position and maximum
acceleration occurs in the MAX position. The acceleration is
continuously variable between these limits.
When the rounding switch in the OFF position, the motor accelerates/
decelerates linearly at the rate set by the ACCEL control. For any
particular setting, the acceleration and deceleration rates are equal.
Rounding
The Rounding control lets you round off the acceleration at the start
and end points. The Rounding control is a 6 position rotary switch
with a knob mounted on the front panel of the ESRS.
No rounding is applied in the OFF position. Minimum rounding
occurs at the next CW position and the maximum rounding is applied
in the MAX position. Within the selected range, the amount of
rounding applied is proportional to the rate of acceleration.
Line Selection
This 3 position toggle switch lets you select whether to use an internal
line, an external line or stop.
INT – Positioning the toggle switch at INT selects the line speed
control mounted in the ESRS.
STOP – Toggling to the STOP position removes all line references and
forces the motor to stop when the acceleration and rounding settings
allow. The STOP position overrides the Enable input and stops the
motor even when the Enable input is active.
