Programming Parameters
5-33
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 (Parm 606). The full numerical range for Parm 607 is 0
to –6 x the value entered in Parm 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 (Parm 606). The full numerical range for Parm 607 is 0
to +6 x the value entered in Parm 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.
