Three Wire Control
When using this control scheme, the factory default for the
reverse function is controlled from TB2. To enable Reverse
operation from the HIM or other serial communication
adapters, Bit 0 of the [Direction Mask] parameter must be
changed from “1” to a “0”. See page 5-48. See Chapter 5 for
general programming instructions.
Two Wire “Run Forward/Run Reverse” Control
To use a two wire ‘‘Run Forward/Run Reverse” control
scheme, Bit 0 of the [Direction Mask] must be set to a ‘‘1.”
For proper operation of the “Run Forward/Run Reverse” mode,
install a jumper across terminals 7 and 8 (Stop) and terminals
11 and 12 (Enable).
3W/2nd Acc and Run F/R 2nd A Control
The HIM module is limited in the number of characters in the
LCD display. Definitions of these functions are as follows.
Refer to Chapter 5, Table 5.A for configuration of switches or
inputs to TB2.
3w/2nd Acc = Three Wire, 2nd Acceleration
Run F/R 2nd A = Run Forward/Reverse, 2nd Acceleration
MOP Function
The MOP function is a digital solid-state circuit that produces
the same effect as rotating a speed reference potentiometer
with a small DC motor. This permits local (HIM) or remote
(TB2) control of the command frequency.
IMPORTANT: The drive can still be started from any adapter
(HIM or a serial device) and will run at the last commanded
direction unless the start, jog and reverse functions of that
adapter have been disabled (See [Start Mask], [Direction
Mask] and [Jog Mask]. See page 5-48 and 5-49.
IMPORTANT:A stop command can be issued from any
adapter at all times.
IMPORTANT:If a Jog is initiated, the drive will Jog in the
direction last traveled.
ATTENTION: Use of the JOG terminal requires
a Bulletin 1201 Human Interface Module or other
Device connection to a drive port, otherwise,
improper operation will occur with Bulletin 1305
firmware FRN 2.01 or lower.
