If the Safety Relay option is installed, there is a dedicated Safety Input @24VDC (user supplied). When 
the Safety Input is asserted, then the hardware will cut the 20V power to the gate drive which will prevent 
all output from the power stage (the Gate Enable LED will turn off). If the user doesn’t need to use the 
Safety Input and the drive has it installed, the user has to bypass it by wiring a 24VDC input to WA (pin 
1) and the return (24VDC) to WB (pin 2).   

There are no software configurable parameters to enable/disable or otherwise 
manipulate the Safety Input functionality. 

 

This connector is used in conjunction with USB A-B cable, which can be purchased from any local 
computer store and is provided when Option 1A is ordered.  The A connector is connected to a PC or Hub 
device; the B connector plugs into the J9-USB port.

This connector is used for Ethernet communications from the Geo PMAC Drive to a PC. 

Delta Tau Systems strongly recommends the use of RJ45 CAT5e or better shielded 
cable. 

Newer network cards have the Auto-MDIX feature that eliminates the need for 
crossover cabling by performing an internal crossover when a straight cable is 
detected during the auto-negotiation process. 

For older network cards, one end of the link must perform media dependent 
interface (MDI) crossover (MDIX), so that the transmitter on one end of the data 
link is connected to the receiver on the other end of the data link (a crossover/patch 
cable is typically used). If an RJ45 hub is used, then a regular straight cable must
