4.1.2c Momentary Start/Stop Switches and Maintain FWD/REV Switch
The diagrammed connections allow remote control to momentarily
start/stop and maintain the motor direction. A Momentary Normally
Open (N.O.) switch is required for starting. A Momentary Normally
Closed (N.C.) switch is required for stopping. A Maintain Switch must
be used for forward/reverse motor control.
Note: If reverse is not
required, the Maintain switch is not necessary.
4.1.2d Reverse Lockout
Allows or prohibits the drive to run in the reverse direction.
Fn03 = X0XX: Reverse is allowed
X1XX: Reverse is prohibited
4.1.3 Terminals 5 & 10
Function: Ground Common
Terminal 5 is the ground common for terminals 3 through 9.
Terminal 10 is the ground common for terminal 11 only.
4.1.4 Terminals 6, 7 & 8
Function: Multifunction Terminals (factory set at preset speeds).
When programmed as preset speed contacts, the drive allows the
user to select up to seven speed points. The frequency (speed) of
each point is set via the digital operator interface. Multispeed control
is described below.
Set multiple speeds as required. If seven speeds or less are required,
set the speed parameters on Speeds 1 to 7. (See Table 4 B). These
terminals also serve other functions such as jog, second accel/decel
time selection, emergency stop, base block, speed search, energy
savings mode enable/disable, control signal source selection, computer
communication control enable/disable, accel/decel prohibit, raise or
lower command, sequence control & speed, and control source
selection. See Fn 56 - Fn58 for details on other uses of the multifunction
digital input contacts.
