Function:
Status Word. Output Relay can be
configured to indicate this warning.
LCP warning light does not light
when this parameter set limit is
reached.
Function:
Enter the I value. When the motor current
LOW
falls below this limit, a bit in the statusword is
set. This value can also be programmed to
produce a signal on the digital output or the
relay output.
Function:
Enter the I value. When the motor
HIGH
current exceeds this limit, a bit in the
statusword is set. This value can also be
programmed to produce a signal on the
digital output or the relay output.
Function:
Enter the lower reference limit. When the
actual reference falls below this limit, the
display reads Ref . The signal outputs
LOW
can be programmed to produce a status
signal on terminal 27 or 29 and on relay
output 01 or 02.
Function:
Use this parameter to set a higher
limit for the reference range.
When the actual reference exceeds
this limit, the display reads
Reference High. Warning bit 19 is set
in 16-94 Ext. Status Word. Output
Relay can be configured to indicate
this warning. LCP warning light does
not light when this parameter set
limit is reached.
Function:
Use this parameter to set a lower
limit for the feedback range.

4-58 Missing Motor Phase Function
Option: Function:
NOTICE
This parameter cannot be adjusted while the
motor is running. Missing Motor Phase
Function is always disabled with PM.
Select On, to display an alarm in the event of a
missing motor phase. Select Off, for no missing motor
phase alarm. However the On setting is strongly
recommended to avoid motor damage.
[0] Off No alarm is displayed if a missing motor phase occurs.
[1] On An alarm is displayed if a missing motor phase occurs.

4.5.4 4-6* Speed Bypass
Define the Speed Bypass areas for the ramps. Some
systems call for avoiding certain output frequencies or
speeds, due to resonance problems in the system. 3
frequency ranges can be avoided.

Function:
Warning When the feedback falls below this
Feedback High] limit, the display reads Feedback
Low. Warning bit 6 is set in 16-94
Ext. Status Word. Output Relay can
be configured to indicate this
warning. LCP warning light does
not light when this parameter set
limit is reached.
Function:
[Depend on Use this parameter to set a higher
limit for the feedback range.
When the feedback exceeds this
limit, the display reads Feedback
High. Warning bit 5 is set in 16-94
Ext. Status Word. Output Relay can
be configured to indicate this
warning. LCP warning light does
not light when this parameter set
limit is reached.
Function:
Some systems call for avoiding certain
output speeds due to resonance problems
in the system. Enter the lower limits of the
speeds to be avoided.
