Amplifier Connections
Amp-Enable, Limit and Home Switch Inputs
Amp Enable Input
The /Enable input functions as an on/off switch for the
drive. When activated the drive functions normally.
When deactivated, the output stages are disabled. If the
motor is turning, and no brake is engaged, the motor will
coast to a stop. The state of the Status LED is also
affected by the /Enable input. If it is activated, and there
are no faults, then the LED will be green. Deactivating
the /Enable will cause the LED to flash green. The active
level and open circuit state, of the enable lines, can be
software configured in the Amp Setup screen.
Travel-limit Inputs (Pos/Neg Enables)
These inputs are typically used with end of travel limit
switches. When a /PosEnable or /NegEnable are
activated the amplifier inhibits further driving into a travel
limit, but still enables the amplifier to back out. Since
motion in one direction is permitted, changing the state of
these inputs has no effect on the status LED.
Home Switch Input
The /Home input is used to detect the home position.
Enable, Limit and Home Input Circuit
The Enable, Limit and Home input circuit (Figure 2-23) is
used to receive the Enable signals: /Enable, /Pos
Enable, /Neg Enable, and /Home. For fail-safe
operation, such as a disconnected or wire broken, a
software command controls the Enable and Home
inputs, pull-up or pull-down level, as a group. This circuit
is designed to work with single-ended TTL signals,
single-ended open-collector signals, and PLCs that
switch to +24V max. or ground.
