Internal impedance	Standstill detection input: Approx. 660 kΩ EDM input: Approx. 2.8 kΩ *3

*1. Input the motor phase-to-phase voltage between Z1 and Z2 and between Z3 and Z4.
*2. When a motor with AC240V or more is used, connect neutral point of the power supply to earth.
*3. Use a contact that is applicable to microloads (24 VDC, 5 mA) for connection to the EDM input.

Outputs

Model	G9SX-SM032-[]
*Safety standstill detection output 1**	Source output (PNP), load current: 0.3 A DC max. * 2
Auxiliary output (output monitor/error)	Source output (PNP), load current: 100 mA DC max.

*1. While safety standstill detection outputs are in the ON state, the following pulse signal is output continuously for output
circuit diagnosis.
When using the safety standstill detection outputs as input signals to control devices (i.e. Programmable Controllers),
consider the pulse signal shown below.

*2. The following derating is required when Units are mounted side-by-side.
G9SX-SM032-[]: 0.2 A max. load current
