Connection to Pulse Motor Amplifier (Clock Up/Down System)
The following circuit diagrams show examples of connections between the LT and a pulse motor amplifier (in
the case where the transistor can be connected to the amplifier).
Output Sink Type
• The circuit of the pulse motor amplifier is illustrated by the DC24V clock up/down sys-
tem. However, the withstand voltage and the operating current of the coupler, which
receives pulse signals, vary by manufacturer. Please contact the amplifier manufacturer
before using.
• The output terminals for LT pulses are the ones that have the signal names OUT0, OUT1,
OUT2, and OUT3. For details of the setting,
please refer to the GP-Pro EX
Reference Manual.
• Output signals for switching do not have to be connected to terminals that accommodate
high-speed output, and can be connected to general-purpose terminals (LT-3200 series:
OUT 4 and OUT5, LT-3300 series: OUT4 through OUT15).
