i.5 Start-Up Programming and Operation
n P4-17: Utility Start Delay
Sets the delay time after power up until the drive will recognize a Run command present within one second of power up or
when the Run command is jumpered on the terminal strip.
This is useful in preventing a peak power surge when multiple drives power up and begin accelerating simultaneously. This
function works when the drives all have different P4-17 settings to spread out the power draw during acceleration.
If the Run command is removed and re-applied during the P4-17 time, the drive will cancel the utility start delay and
immediately begin running.
The Utility Start Delay is applied when the drive is auto-restarting after an Undervoltage (Uv) or an Overvoltage (ov) condition.
No.
P4-17
n P5-02: HAND Reference 1
Sets the frequency reference of HAND mode. When the drive is stopped, pressing the HAND key will start the drive and the
drive will accelerate to the P5-02 setting.
No.
P5-02
n P5-04: HAND Key Function Selection
Selects whether the HAND key on the HOA keypad is active. Disabling this function by setting P5-04 to 0 will prevent the
drive from entering HAND Mode.
No.
P5-04
Setting 0: Disabled
Setting 1: Enabled
n Q1-01: PID Controller Setpoint 1
Sets the PID setpoint for the controller. The drive will use the system feedback signal and modulate the pump speed to regulate
the feedback at the Q1-01 setpoint. The units for Q1-01 are selected by b1-01 and the scaling is set in parameter P1-03. This
parameter is active when b1-01 (Reference Source) is set to 0 (HOA keypad).
No.
Q1-01
u
No-Load Operation Test Run
This section explains how to operate the drive with the motor decoupled from the load during a test run.
n Before Starting the Motor
Check the following items before operation:
• Ensure the area around the motor is safe.
• Ensure external emergency stop circuitry is working properly and other safety precautions have been taken.
n During Operation
Check the following items during operation:
• The motor should rotate smoothly (i.e., no abnormal noise or oscillation).
• The motor should accelerate and decelerate smoothly.
u
Test Run with the Load Connected
After performing a no-load test run, connect the motor and proceed to run the motor and load together.
n Checklist Before Operation
• The motor should rotate in the proper direction.
