General Programmable Input Functions
Other inputs, depending on the selected mode of operation, may also have pre-defined functions,
as described in
Mode-Dependant Dedicated Inputs
(p.
70)
. The remaining inputs can be
programmed to functions listed below.
Function Description
NEG Limit-HI Inhibits
When input is high, amplifier inhibits motion in negative direction.
NEG Limit-LO Inhibits
When input is low, amplifier inhibits motion in negative direction.
POS Limit-HI Inhibits
When input is high, amplifier inhibits motion in positive direction.
POS Limit-LO Inhibits
When input is low, amplifier inhibits motion in positive direction.
Reset on LO-HI Transition
Amplifier resets on the low-to-high transition of the input.
Reset on HI-LO Transition
Amplifier resets on the high-to-low transition of the input.
Motor Temp HI Disables
When the input is high, amplifier generates a
Motor Over Temperature
fault (which
disables the PWM output stage).
Motor Temp LO Disables
When the input is low, amplifier generates a
Motor Over Temperature
fault (which
disables the PWM output stage).
Home Switch Active HI
When the input is high, the home switch is activated.
Home Switch Active LO
When the input is low, the home switch is activated.
Motion Abort Active HI I
When the input is high, motion stops but the amplifier remains enabled. Any
position or velocity commands received while the input is active are ignored.
In position mode, upon activation of the input, the motor will decelerate at the
trajectory abort deceleration rate to zero velocity and then hold current position.
In velocity mode, upon activation of the input, the motor will decelerate to zero
velocity at the velocity fast stop ramp rate and then hold zero velocity.
In current mode, the input has no effect.
Motion Abort Active LO
When the input is low, motion stops but the amplifier remains enabled. Any
position or velocity commands received while the input is active are ignored.
In position mode,, upon activation of the input, the motor will decelerate at the
trajectory abort deceleration rate to zero velocity and then hold current position.
In velocity mode, upon activation of the input, the motor will decelerate to zero
velocity at the velocity fast stop ramp rate and then hold zero velocity.
In current mode, the input has no effect.
Hi Res Analog Divide Active HI
A high input causes the firmware to divide the level of the analog input signal by 8.
Hi Res Analog Divide Active LO
A low input causes the firmware to divide the level of the analog input signal by 8.
PWM Sync Input
Receives the PWM sync output of a master amplifier. For more information, see
Synchronizing PWM Switching Frequency (p. 18)
. (Only on high-speed inputs.)
