Control Wiring Block Diagram Notes
(1)
Important: I/O Terminal 01 is always a coast to stop input except when P036 [Start
Source] is set to “3-Wire”, “2-W Lvl Sens” or “Momt FWD/REV” control. In three wire
control, I/O Terminal 01 is controlled by P037 [Stop Mode]. All other stop sources are
controlled by P037 [Stop Mode].
Important: The drive is shipped with a jumper installed between I/O Terminals 01 and
11. Remove this jumper when using I/O Terminal 01 as a stop or enable input.
(2)
Two wire control shown. For three wire control use a momentary input on I/O
Terminal 02 to command a start. Use a maintained input for I/O Terminal 03 to
change direction.
(3)
The function of I/O Terminal 03 is fully programmable. Program with E202 [Digital
Term 3].
(4)
Match the Voltage Range Select DIP switch setting with the control scheme for proper
Uni-Polar or Bipolar operation.
(5)
When using an opto output with an inductive load such as a relay, install a recovery
diode parallel to the relay as shown, to prevent damage to the output.
(6)
When the ENBL enable jumper is removed, I/O Terminal 01 will always act as a
hardware enable, causing a coast to stop without software interpretation.
