Chapter 5: Keypad Menu Items and Parameters
5.4.11 – ‘Parameters’ Menu (continued)
(reserved)
(reserved)
(reserved)
Status 5
Range: 0 to 255 (flags) Default: 0 Scaling: 1 Type: R
‘Status 5’ flags – Read this parameter by individual bits.
• Bit #:
0: Over Temperature –
inhibits re-start if set; effectively the heatsink is too hot to start, but is OK to run.
1: Offline Command Fail –
the last offline command failed; automatically resets when the next command is attempted.
2: (unused)
3: Fan Status – used in conjunction with an output relay to control fans
4: (unused)
5: (unused)
6: (unused)
7: (unused)
UserFlags 4
Range: 0 to 255 (flags) Default: 0 Scaling: 1 Type: R/W
‘User Flags 4’ is a fourth set of individual bits for user control or system status.
(Other ‘User Flags’ are parameters 51, 52, 53, 95, & 96.)
• Bit #:
0: Impact Load – limit max delay adjustment in optimizing for highly volatile loads.
1: (unused)
2: Auto Soft Stop Smoothing – Enable P-122 Soft Stop Smoothing for pumps.
3: Breaker Present (Line Contactor)
If the starter is to be used with a circuit breaker, then set bit 3 to a one (1).
Read the description of the “Line Contactor” Menu Item in section 5.4.5 (“Advanced Menu”) for a
more detailed explanation of this functionality.
• 0 = ‘Line Contactor’
• 1 = ‘Breaker Present’
4: Op – gains the maximum amount of energy savings on variable loads.
• Requires an external user-supplied bypass contactor and current transformer
• Associated with P109 Upper Limit and P110 Lower Limit
When motor is lightly loaded as set in P110, the bypass contactor is de-energized to run the motor
from the soft starter in Energy Optimizing mode. When motor is heavily loaded as set in P109, the
bypass contactor is energized to eliminate the soft starter thyristor losses.
5: Quick Ramp Times – selects ramp times to be 10 times faster than the value entered,
although min = 0.3 seconds.
6: Two Stop Bits – when set, the comms will have two stop bits.
7: Auto Stop (2) – alternative stopping method.

‘Op’ requires an external user-supplied bypass contactor and current
transformer. See Electrical Installation Chapter 2, subsections 2.4.1 & 2.5.2 for details.
