Wiring example
When the Gate Suppress function is utilized, connect the drive to a safety certified
interrupting device utilizing EDM output signal to reconfirm both safety inputs GS1 and
GS2.
Safety input
Safety Switch
(Example: emergency
push button)
By pressing the emergency stop button, the current to GS1 and GS2 is shut off, and the
inverter output is shut off. By this, motor is free-running. This behavior is according to the
stop category 0 defined in EN60204.
Note 1: Above is the example to use the intelligent input terminal with source logic. When
it is used with sink logic, the wiring is to be modified.
Note 2: The wire for safety relay and emergency input signal are to be shielded coaxial
cable for example RS174/U (produced by LAPP) by MIL-C17, or KX2B by NF C
93-550 with diameter 2.9mm with less than 2 meters. Please be sure to ground
the shielding.
Note 3: All the inductance related parts such as relay and contactor are required to
contain the over-voltage protection circuit.
The arch extinguishing fuse with rated voltage AC250V, rated current 100mA complies
to either IEC6127 –2/-3/-4

SOC EQ series AC250V, 100mA (UL, SEMKO, BSI)
Little 216 series AC250V, 100mA (CCC, UL, CSA, SEMKO, CE, VDE)
