4-24 FlexPak 3000 DC Drive Software Reference
SPD LOOP REFERENCE (P.295)
The final speed loop
reference value used
by the speed loop
regulator in the drive. Parameter Range: n/a
Default Setting: n/a
Parameter Type: Output
OIM Menu Path(s): SPD - Speed/Voltage Loop ( SPD ) Test Points
Drive Reference - Drive Reference Test Points
TOP SPEED
(P.011)
The highest running
speed of the motor.
This input is the basis
of speed loop scaling. Parameter Range: 5 to 5000 RPM
Default Setting: 500 RPM
Parameter Type: Configurable
OIM Menu Path(s): Drive Reference - Drive Reference Limits
Quick Start
TOP SPEED depends on several factors:
• If there is no field weakening, the top speed is typically the same as the motor
nameplate base speed.
• If there is field weakening, the top speed is the same as the field-weakened
speed. Top speed is typically more than the base speed when field weakening is
applied.
Whenever TOP SPEED is changed, you should check the positions of jumpers J11
and J14 to make sure they are set as indicated by J11 ANLG TACH VLT SCL (P.792)
and J14 ANLG TACH VLT RNG (P.793). The tachometer wiring might also need to be
changed. See the hardware manual for more information.

ATTENTION: Before starting the drive, this parameter must be set to
base speed or (if the Field Current Regulator kit is installed) the field
weakened speed. The user is responsible for assuring safe conditions
for operating personnel by setting this parameter properly. Failure to
observe this precaution could result in bodily injury.
ATTENTION: Do not allow the motor to exceed the maximum safe speed
of the motor or driven equipment as determined by the equipment
manufacturer. Failure to observe this precaution could result in bodily
injury.
