Programming Parameters
7-33
Parameter 606 – Base Motor Speed [Base Motor Speed]
Internal units : RPM
Programming Terminal units: RPM
Minimum Value: 1
Maximum Value: 6000
Default Value: 1750
Description : Nameplate base motor speed in RPM.
Parameter 607 – Reverse Speed Limit [Rev Speed Limit]
Internal units : 4096 = 1000h = 1 pu = base motor speed
Programming Terminal units: RPM
Minimum Value: – 6 x base speed
Maximum Value: 0
Default Value: – base speed
Description : This parameter sets a limit on velocity reference in the
negative direction and is dependent on the value entered for Base
Motor Speed (Parameter 606). The full numerical range for
Parameter 607 is 0 to – 6 x the value entered in Parameter 606. The
reverse motor speed will not be allowed to exceed this value. This
parameter is also used together with the absolute overspeed parameter
to determine when an absolute overspeed fault will occur. Note that
the value entered for this parameter must be negative.
Parameter 608 – Forward Speed Limit [Fwd Speed Limit]
Internal units : 4096 = 1000h = 1 pu = base motor speed
Programming Terminal units: RPM
Minimum Value: 0
Maximum Value: 6 x base speed
Default Value: base speed
Description : This parameter sets a limit on velocity reference in the
positive direction and is dependent on the value entered for Base
Motor Speed (Parameter 606). The full numerical range for
Parameter 607 is 0 to +6 x the value entered in Parameter 606. The
forward motor speed will not be allowed to exceed this value. This
parameter is also used together with the Absolute Overspeed
Parameter to determine when an Absolute Overspeed Fault will occur.
Parameter 609 – Encoder PPR [Encoder PPR]
Internal units : pulses per revolution
Programming Terminal units: PPR
Minimum Value: 100
Maximum Value: 32767
Default Value: 1024
Description : Pulse Per Revolution rating of feedback device when
using an encoder mounted on the motor. The encoder is used to
determine motor feedback velocity.
