Speed Display Scaling; Elapsed Time Meter Output; Elapsed Time Meter Reset - Reliance electric GV3000/SE Instruction Manual

P.028

Speed Display Scaling

Parameter Range: 10 - 9999
Initial Setting: V/Hz mode: 1500 (=50 Hz) Synchronous speed based on H.001
Vector mode: 1400 (=1400 RPM) U.017 (Motor Top Speed)
Type: Tunable (at rest or during operation)
Refer to: U.017
H.001
Description:
This parameter defines the scaling value (speed or any engineering unit) to be used when
displaying at keypad display SPEED in monitor mode.
The value in this parameter will become the max. displayed value for the SPEED monitor mode.
Use the following formulas to solve for the current operating speed or frequency if you have scaled
the SPEED display.
• Vector:
Current Operating Speed in RPM * P.028
U.017 (Motor Top Speed))
Current Operating Speed in Hz * P.028
• V/Hz:
Example:
Your application requires the display to be scaled to show the maximum speed as 800 liters /
minute. Assume Vector Mode is activated.
Parameter U.017 is set to 1450, parameter P.004 is set to 1450.
1. Set parameter P.028 = 800.
2. Enter the SPEED monitor mode by pressing the PROGRAM key until the PROGRAM LED
turns off and the SPEED LED turns on. For Keypad operations refer to Section 3.
3. Start the drive (press the START key).
4. When the drive is running at rated speed, the display shows that speed is 800 liters/minute.
If you choose for current speed above, your result will be 1450.
P.029

Elapsed Time Meter Output

Parameter Range: 0 - 9999 days
Type: Read only drive output
Refer to: P.030 Elapsed Time Meter Reset
Description: This parameter displays the number of days (24-hour periods) that the drive has
been under power or the time elapsed since the Elapsed Time Meter Reset (P.030)
parameter was last reset.
P.030

Elapsed Time Meter Reset

Parameter Range: OFF = No action.
ON = Reset the Elapsed Time Meter (P.029 ) and the error log clock to zero (0).
Initial Setting: OFF
Type: Tunable (at rest or during operation)
Refer to: P.029 Elapsed Time Meter Output
Description: This parameter sets parameter P.029 (Elapsed Time Meter) and the error log clock
to zero. This parameter is set to OFF after the reset operation is carried out.
