TORQUE ENABLE SAFETY CIRCUITRY
80 IPA Hardware Installation Guide
User Connections
The Torque Enable terminals are on the Auxiliary connector mounted on the top of the IPA. Terminal
designations are:
Signal Pin Description
TRQ_EN1 2 Torque enable input 1
TRQ_EN2 3 Torque enable input 1
TRQ_EN_24V* 4 Bypass power for TE (limited to 30mA)
/TRQ_EN1 8 Negative input torque enable input 1
/TRQ_EN2 9 Negative input torque enable input 2
TRQ_EN_COM 10 Common for TRQ_EN_24V
Warning: The IPA comes with the Torque Enable connector pre-wired to
always enable the drive’s ability to provide torque. In order to
disable torque and wire the drive to your safety system, you
must remove the two 3-pronged jumpers between pins 2, 3, 4
and pins 8, 9, 10.
The IPA pin TRQ_EN_24V is internally limited to 30mA and is
intended only as a bypass of the Torque Enable circuitry for
those applications wishing to disable this feature. Do not power
external circuitry with this output.
