POSITIVE CURRENT LIM (P.005)
Selects the highest amount of current (% motor rated armature amps) for the forward bridge. May also
be selected as high limit for the Speed Loop PI block output (P.223). See NEGATIVE CURRENT LIM
(P.006) for information regarding the operation of the current limit registers.
Parameter Range: 0 to MAXIMUM CURRENT (%FLA)
Default Setting: 150 %FLA
Parameter Type: Tuneable
OIM Menu Path(s): Current Minor Loop (CML) - CML Tuning
Speed/Voltage Loop (SPD) - Speed/Voltage Loop (SPD) Tuning
Quick Start
Refer also to Parameters: NEGATIVE CURRENT LIM (P.006) NEG CUR LIM INV EN (P.226)
POS CURRENT LIM SEL (P.223)
PRESET SPEED 1, 2, and 3 (P.117, P.118, & P.119)
Only available if the I/O Expansion kit is installed.
These parameters set up to three preset speed references when the REGULATOR TYPE jumper (J15
on the regulator board) is set for the speed/voltage control loop. To use these speeds, CONTROL
SOURCE SELECT must be set to TERMBLK.
Parameter Range: MINIMUM SPEED to MAXIMUM SPEED (speed user units)
Default Setting: 250 RPM
Parameter Type: Tuneable
OIM Menu Path(s): Drive Reference - Drive Reference Configure
Refer also to Parameters: CONTROL SOURCE SELECT(P.000)
DIG IN 1 (P.495)
DIG IN 2 (P.496)
MAXIMUM SPEED (P.004) MINIMUM SPEED (P.003)
The preset speeds are selected through digital input 1 and digital input 2 on the I/O Expansion board, as
shown in the following table.
Digital Input
1(Terminal 59) Digital Input
2(Terminal 60) Speed/Voltage Loop Reference
OFF OFF Selected AUTO or MANUAL reference
ON OFF PRESET SPEED 1 (P. 117)
OFF ON PRESET SPEED 2 (P. 118)
ON ON PRESET SPEED 3 (P. 119)
If the I/O Expansion Kit is not installed, the digital inputs are set to OFF and cannot be changed and the
AUTO or MANUAL reference is used for the speed reference. The selected preset speed reference
passes through the same control blocks as other speed references.
PULSE TACH PPR (P.207)
Pulse tachometer pulses per revolution (PPR) from the pulse tachometer nameplate.
Supported in regulator firmware version 1.10 or higher.
Parameter Range: 18 to 2500 PPR
Default Setting: 18 PPR
Parameter Type: Configurable
OIM Menu Path(s): Speed/Voltage Loop (SPD) - Speed/Voltage Loop (SPD) Feedback
WARNING
The incorrect setting of this parameter can cause an overspeed condition. This parameter must be set
by a qualified person who understands the significance of setting it. Set the value of this parameter
accurately per your application requirements. Failure to observe this precaution could result in bodily
injury.
