Output Terminals
Table 15 lists the output terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
output.
Note: Multi-function relay output terminals are rated at a minimum of 10 mA. If less than 10 mA is required, use the photocoupler
outputs (P1-C1, P2-C2). Using the wrong current output level may cause the output to malfunction when the terminal is activated.

Type
<1> Refrain from assigning functions to terminals M1 thru M6 that involve frequent switching, as doing so may shorten relay performance life.
Switching life is estimated at 200,000 times (assumes 1 A, resistive load).
<2> Connect a suppression diode as shown in Figure 25 when driving a reactive load such as a relay coil. Make sure the diode rating is greater than
the circuit voltage.
<3> Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN 61800-5-1,ISO/EN
13849 Cat.3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
