 +
==Examples==
 +
===Wiring axis limit and home switches to J5===
 +
To operate the motor, limit switches must be connected to the GPI1 and GPI2. Feeding logic 1 to one of these ports enables axis motion feed in certain direction.
 +
 
 +
The behavior of feed enable signals can be configured via [[Granity user guide/Machine|Granity machine tab]]. Logic 1 to these pins is required for drive operation:
 +
*GPI1 - enable positive direction feed.
 +
*GPI2 - enable negative direction feed.
 +
Home switch (optional):
 +
*GPI3 - home switch input. Polarity can be configured via Granity.
 +
 
 +
In the image below A way to connect switches to J5 port. Inputs are supplied by the J5 connector 5V output. Alternatively the switches may be also supplied from an external 5-24VDC supply.
 +
 
 +
[[File:J5switches.png|500px]]
 +
 
 +
The example below illustrates an alternative way of connecting limit switches that are connected in series. However this way requires that axis is being manually pulled away from end of travel if either switch is open as drive doesn't know which way is the safe running direction.
 +
 
 +

Examples[edit | edit source]

Wiring axis limit and home switches to J5[edit | edit source]

To operate the motor, limit switches must be connected to the GPI1 and GPI2. Feeding logic 1 to one of these ports enables axis motion feed in certain direction.

The behavior of feed enable signals can be configured via Granity machine tab. Logic 1 to these pins is required for drive operation:

  • GPI1 - enable positive direction feed.
  • GPI2 - enable negative direction feed.

Home switch (optional):

  • GPI3 - home switch input. Polarity can be configured via Granity.

In the image below A way to connect switches to J5 port. Inputs are supplied by the J5 connector 5V output. Alternatively the switches may be also supplied from an external 5-24VDC supply.

The example below illustrates an alternative way of connecting limit switches that are connected in series. However this way requires that axis is being manually pulled away from end of travel if either switch is open as drive doesn't know which way is the safe running direction.

J5switches2.png

Alternative limit switch wiring considerations[edit | edit source]

It is possible to connect limit switches several way, or omit them completely. The table below summarizes the different methods:

Method # Connections / configurations End of travel causes a fault stop state End of travel causes active braking of motor Can move motor electrically out end of travel Remarks
A Connect limit switches independently to GPI2 and GPI3 inputs Yes (but depends on parameterization) Yes (but depends on parameterization) Yes This is the most typical method used
B Connect limit switches in series to GPI2 and GPI3 inputs parallel Yes (but depends on parameterization) Yes (but depends on parameterization) No Drive has info only that limit switch is open but no info about which way is safe to move
C No limit switches, instead use homing function (position control mode only) and set soft travel limits by parameterization No Yes Yes Sensorless & wireless solution
D Connect limit switches Safe torque off input Yes No, motor may free wheel No A very secure way to remove torque from motor. If such feature is desired, it's recommended to install second pair of limit switches or use soft travel limits that stop motion before the STO switches, so STO switches would serve only as backup.

Analog signal setpoint[edit | edit source]

This example shows how to wire a typical single ended Analog setpoint controller. Maximum analog signal voltage is +/-10V.

0-10V analog input with digital direction signal[edit | edit source]

Follow the earlier guidelines but connect controller's direction signal to ANAIN2+ and the ground reference of digital output to ANAIN2-. Setpoint gets inverted inside the drive if ANAIN2 voltage is between 3-24VDC and non-inverted between 0-3VDC. May require FW upgrade.

  • Pulse & direction set point
  • Clear faults output (off-on-off pulse generated by controller user if FAULT input goes on)
