3.6 Control Circuit Wiring
u 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 3.1 .
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. Failure to comply may result in death or serious injury.

Photocoupler
24 Vdc, 8 mA
Note: Drive preset to sinking mode. When using source mode, set
DIP switch S3 to allow for a 24 Vdc (±10%) external power supply.
Refer to Sinking/Sourcing Mode Switch on page 79 for details.
S2 Multi-function input 2 (Not used/Through mode)
S3 Multi-function input 3 (External pump fault (N.O.)
S4 Multi-function input 4 (Fault reset)
S5 Multi-function input 5 (Multi-step speed reference 1)
S6 Multi-function input 6 (HAND Mode)
S7 Multi-function input 7 (HAND Mode 2)
SC Multi-function input common (Control common) Sequence common
Safe Disable
Input
HC Power supply for safe disable input +24 Vdc (max 10 mA allowed)
H1 Safe disable input
Open: Output disabled
Closed: Normal operation
Note: Disconnect wire jumper between HC and H1 when using the
safe disable input. The wire length should not exceed 30 m.

<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).
