Control Circuit Terminal Block Functions
Drive parameters determine which functions apply to the multi-function digital inputs (S1 to S7), multi-function digital
outputs (MA, MB), multi-function pulse inputs and outputs (RP, MP) and multi-function photocoupler outputs (P1, P2).
The default is called out next to each terminal in Figure 3..
WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being wired. Operating a drive
with untested control circuits could result in death or serious injury.
WARNING! Confirm
the drive I/O signals and external sequence
before starting test run. Setting parameter A1-06 may change the I/O
terminal function automatically from the factory setting. Refer to Application Selection on page 94. Failure to comply may result in
death or serious injury.

<1> Do not assign functions to digital relay outputs that involve frequent switching. This 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 3.17 when
driving a reactive load such as a relay coil. Ensure the diode rating is greater than
the circuit voltage.
<3> When set for sourcing. +5 V/1.5 kΩ or higher, +8 V/3.5 kΩ or higher, +10 V/10 kΩ or higher.
<4> When set for sinking, the external power supply should be +12 Vdc, ±5% with 16 mA or less.
