– Probe 1&2 Input, 24 Vdc Probe/Proxy
Feed for pin assignment.
The D-SUB 9-WAY X15 connector on the AMD5x Drive has provision for two separate Probe Inputs and a
dedicated 24 Vdc power source intended for use with Probes or Proxy switches. A feature of the 24 Vdc power
source not only means that probe/proxy wiring is simplified, but more importantly, noise free probe/proxy
operation can be achieved since the 24 Vdc
feed is “clean”, and free of noise usually present on general use 24
Vdcsupplies in the electrical cabinet.
The 24 Vdc source (PROBEX designation on X15) is obtained from pins 4, 5, and 6, and can be used to supply
either/or both Probe/Proxies. The ProbeX 24 Vdc output is rated at 200mA, and is short-circuit protected (self-
resetting fuse). In addition, this 24 Vdc output is monitored by the DSP so that short-circuit faults are detected.
The pin assignment accommodates the use of three internally shielded pairs, and one external shield. This cable
format is strongly recommended for Probe/Proxy wiring.
A Proxy switch can be used instead of a full Encoder, where only simple speed-sensing is required. The
maximum frequency that the drive can monitor through the proxy input is 4000 Hz.
