Nidec Digistart D4 User Manual

Programmable Parameters
2J – Multi Pump
Options: Single Pump (default)
Manifold Pump
Description: Adjusts the performance of adaptive control to suit installations with multiple
pumps connected to a common outlet manifold.
2K – Start Delay
Range: 0:00 - 60:00 (minutes:seconds) Default: 0 second
Description: Sets a delay after the starter receives a start command, before it starts the
motor.
9.7 5 Protection Levels
5A – Current Imbalance
Range: 10% - 50% Default: 30%
Description: Sets the trip point for current imbalance protection.
5B – Current Imbalance Delay
Range: 0:00 - 4:00 (minutes:seconds) Default: 3 seconds
Description: Slows the soft starter's response to current imbalance, avoiding trips due to
momentary fluctuations.
5C – Undercurrent
Range: 0% - 100% Default: 20%
Description: Sets the trip point for undercurrent protection, as a percentage of motor full
load current. Set to a level between the motor's normal working range and
the motor's magnetising (no load) current (typically 25% to 35% of full load
current). A setting of 0% disables undercurrent protection.
5D – Undercurrent Delay
Range: 0:00 - 4:00 (minutes:seconds) Default: 5 seconds
Description: Slows the soft starter's response to undercurrent, avoiding trips due to
momentary fluctuations.
5E – Overcurrent
Range: 80% - 600% Default: 400%
Description: Sets the trip point for overcurrent protection, as a percentage of motor full
load current.
5F – Overcurrent Delay
Range: 0:00 - 1:00 (minutes:seconds) Default: 0 second
Description: Slows the soft starter's response to overcurrent, avoiding trips due to
momentary overcurrent events.
5G – Excess Start Time
Range: 0:00 - 4:00 (minutes:seconds) Default: 20 seconds
Description: Excess start time is the maximum time the soft starter will attempt to start
the motor. If the motor does not transition to Run mode within the
programmed limit, the starter will trip. Set for a period slightly longer than
required for a normal healthy start. A setting of 0 disables excess start time
protection.
