User Current Maximum Scaling; Low Speed Thermal Protection Mode; Percentage Torque; Reduce Internal Current Loop Response - Emerson 2202 Advanced User's Manual

Parameter Parameter
Introduction

4.24

User current maximum scaling

Bit SP
Coding
Range 0.0 to TORQUE_PROD_CURRENT_MAX%
Default 165.0
Update rate Background
The maximum for Pr 4.08 and Pr 4.20 is defined by this parameter.
4.25

Low speed thermal protection mode

Bit SP
Coding
1
Range OFF(0) or On(1)
Default OFF(0)
Update rate Background
0: OFF Low speed thermal protection mode disabled
1: On Low speed thermal protection mode enabled
See Pr 4.16 on page 68 for details.
4.26

Percentage torque

Bit SP
Coding
Range ±USER_CURRENT_MAX %
Update rate Background
Pr 4.26 shows the torque producing current (Pr 4.02) as a percentage of the active torque producing current, but with an additional adjustment above
base speed so that this parameter shows percentage torque. Below base speed, Pr 4.26 is equal to Pr 4.20. Above base speed the percentage
torque producing current (Pr 4.20) is adjusted as follows:
Pr 4.26 = Pr 4.20 x motor rated frequency (Pr 5.06) /post ramp reference (Pr 2.01)
4.27

Reduce internal current loop response

Bit SP
Coding
1
Range OFF (0) or On (1)
Default OFF (0)
Update rate Background
Modification of this parameter may be required when using the drive with a high- speed motor, which inherently has low inductance.
This parameter should only be set to On if OI.AC trips are occurring when the drive is carrying out a mains loss stop or DC injection brake with a high
speed motor.
NOTE
Only available with drive firmware V01.08.04 onwards (size 2 to 6).
