3.7 Control Circuit Wiring

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.

Digital Inputs
S1
Multi-function input 1 (Closed: Forward run, Open:
Stop)
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 59 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.
