DIGITAL INPUTS
has nine digital inputs, eight of which have programmable functions. Input [IN1] is not programmable and is dedicated to the drive
Enable function. This is done to prevent accidental programming of the input in such a way that the controller could not shut it down.
Two types of RC filters are used: GP (general purpose) and HS (high speed). Input functions such as Step/Direction, CU/CD, Quad A/B are wired to
inputs having the HS filters, and inputs with the GP filters are used for general purpose logic functions, limit switches, and the motor temperature sensor.
Programmable functions of the digital inputs include :
• Positive Limit switch
• Negative Limit switch
• Home switch
• Drive Reset
• PWM current or velocity commands
• CAN address bits
In addition to the active level and function for each programmable input, the input resistors are programmable in three groups to either pull up to +5 Vdc,
or down to ground. Grounded inputs with HI active levels interface to PLC's that have PNP outputs that source current from +24 Vdc sources. Inputs pulled
up to +5 Vdc work with open-collector, or NPN drivers that sink current to ground.

DIGITAL OUTPUTS
Digital outputs are open-drain MOSFETs with 1 kΩ pull-up resistors to +5 Vdc. These can sink up to 100 mAdc
from external loads operating from power supplies to +30 Vdc. When driving inductive loads such as a motor
brake, an external fly-back diode is required. The diode in the output is for driving PLC inputs that are opto-
isolated and connected to +24 Vdc. The diode prevents conduction from +24 Vdc through the 1 kΩ resistor to
+5 Vdc in the drive. This could turn the input on, giving a false indication of the drive output state.
These outputs are programmable to be on or off when active. Typical functions are drive fault indication or
motor brake operation. Other functions are programmable.
