Programming Parameters
7-60
Parameter 708 – At Speed 5 [At Speed 5]
Internal units : 4096 = 1000h = 1 pu = base motor speed
Programming Terminal units: RPM
Minimum Value: – 6 x base speed
Maximum Value: +6 x base speed
Default Value: base speed rpm
Description: This parameter is used to specify the at speed 5 setpoint
in the logic status (Parameter 100, bit 15). This 1 bit field is set to 1
when the actual velocity of the motor is greater than the at speed 5
setpoint. Otherwise, set to 0. Internally, if the Velocity Feedback
(Parameter 106) is greater than or equal to At Speed 5 (Parameter
708), the At Speed 5 bit 15 is set to 1. Otherwise it is set to 0.
Parameter 709 – Up To Speed Tolerance [Up to Speed Tol]
Internal units : 4096 = 1000h = 1 PU = base motor speed
Programming Terminal units: RPM
Minimum Value: 0 rpm
Maximum Value: + base speed / 10
Default Value: base speed / 100
Description: This parameter establishes a band around the At Speed
setpoints (Parameters 704 to 708) that will be used to determine when
to update the At Speed bit, Parameter 100 bits 11 – 15 and the At Set
Speed bit, Parameter 100 bit 9 in the Logic Status word. Refer to the
descriptions for the At Speed setpoints for more information.
Parameter 710 – Zero Speed Tolerance [Zero Speed Tol]
Internal units : 4096 = 1000h = 1 PU = base motor speed
Programming Terminal units: RPM
Minimum Value: 0 rpm
Maximum Value: 6 x base speed
Default Value: base speed / 100
Description: This parameter establishes a band around zero speed
that will be used to determine when to update the At Zero Speed bit,
Parameter 100, bit 10 in the Logic Status word. This output is
checked using the same method as At Speed 1 and 2 except the set
point is fixed at zero speed.
Parameter 711 – Jog Dwell [Jog Dwell]
Internal units : Seconds x 10
Programming Terminal units: Seconds
Minimum Value: 0.0
Maximum Value: 6553.5
Default Value: 0
Description: This parameter specifies dwell time before the
contactor opens after completing a jog function.
