The following table provides a description of the digital input
specifications.
On SERCOS drives, the following inputs have dedicated functionality.
On non-SERCOS drives, digital inputs can be configured for a variety
of functions using Ultraware. Refer to Ultraware Help for digital input
functionality.
Assigned Preselect Inputs
Active or inactive states select one of 64 presets shown in the
following binary table. Active state indicates current flow through the
input optocoupler. Inactive state indicates no current flow.
Parameter Description Minimum Maximum
ON State Voltage
Voltage applied to the input, with respect to
IOCOM, to guarantee an ON state.
10.8.V 26.4V
ON State Current Current flow to guarantee an ON State 3.0 mA 12.0 mA
OFF State Voltage
Voltage applied to the input, with respect to
IOCOM, to guarantee an OFF state.
-1.0V 2.0V
Propagation Delay
Signal propagation delay from the digital
input to the firmware-accessible registers.
— 100 μS
Pin Signal Description
CN1-31 ENABLE
Drive Enable Input, an active state enables the power electronics to control
the motor.
CN1-32 HOME
Home Sensor, an active state indicates to a homing sequence that the
sensor has been seen.
CN1-33
CN1-34
REG1
REG2
Registration Sensor, a transition is used to record position values.
CN1-37
CN1-38
OT_POS
OT_NEG
Overtravel Input, an inactive state indicates that a position limit has been
exceeded. An active state occurs when 24V is removed from the input.
IMPORTANT
Overtravel limit input devices must be normally
closed.
