ATTENTION: If a normal drive start command is received while the drive is jogging, the drive will switch from jog mode to run mode.
The Speed Select input function configuration process involves assigning the functionality of the three possible Speed Select input functions to physical digital inputs. The three Speed Select inputs functions are called Speed Select 1, Speed Select 2, and Speed Select 3, and they are assigned to physical inputs using the Digital In”x” Sel parameters. Table 4.6 on page 78 describes the various reference sources that can be selected using all three of the Speed Select input functions.
23, 24 = MOP Increment, MOP Decrement: The MOP is a reference setpoint (called the MOP Value) that can be incremented and decremented by external devices. These inputs are used to increment and decrement the Motor Operated Potentiometer (MOP) value inside the drive. The MOP value will be retained through a power cycle. While the MOP Increment input is closed, the MOP value will increase at rate contained in MOP Rate. Units for rate are Hz per second.

5.4 About Faults Faults indicate conditions within the drive that require immediate attention. The drive responds to a fault by initiating a coast-to-stop sequence and turning off output power to the motor. In addition, some faults are auto-resettable, non-resettable, and/or user-configurable as described in table 5.5. Type Table 5.
The drive indicates faults in the following ways: • Inverter Status LED on the drive control panel (see section 5.2). • Drive status parameters Drive Status 1 (209) and Drive Status 2 (210). • Entries in the fault queue (see section 5.4.1). • Pop-up screen on the LCD OIM. See figure 5.3. The screen displays: • Fault number • Fault name • Time that has elapsed since fault occurred.
Refer to section 5.8.1 for information on accessing the fault queue using the LCD OIM.
