You can use the default parameter setting with the P499RxP-107C transducer and R410a refrigerant within a range of operation that depends on the specific model of P499 transducer selected. All other applications require some parameter changes and may require different transducers.

Table 1. Parameter Descriptions for VFD68Dxx Drives
Parameter Indication on Monitor Description Settings Default Setting
P. 0 Torque Boost: Defines the voltage (% total V) applied to the motor when the drive starts the motor at 0 Hz. 0–30% 4% or 3%
P. 1 Maximum Frequency: Defines the maximum speed of the motor in your application. See Figure 1. 0–120 Hz 60 Hz
P. 2 Minimum Frequency: Defines the minimum speed of the motor in your application.1 See Figure 1. 0–120 Hz 12.5 Hz
P. 3 Base Frequency: Set parameter to the rated frequency [Hz] on motor rating plate. 0–400 Hz 60 Hz
P. 7 Acceleration Time: Defines the time required to accelerate from stop (0 Hz) to full rated RPM (60 Hz). 0–3600 seconds 15 seconds
P. 8 Deceleration Time: Defines the time required to decelerate from full rated RPM (60 Hz) to stop (0 Hz). 0–3600 seconds 15 seconds
P. 9 Motor Rated Current: Set parameter to the rated FLA on motor rating plate. 0–500 A Rated VFD68 Output
P. 19 VFD Output Voltage: Defines the maximum output voltage relative to the drive's supply voltage.2
  • 9999: the maximum output voltage is the same as the drive's power supply voltage
0–1000V, 9999 9999
P. 22 Stall Prevention Output Current Level: Defines the current level (as a % of motor FLA) at which the drive begins to adjust the output frequency (Hz) to reduce the output current. 0–200% 150%
P. 31 Frequency Jump 1A: Frequency Jump parameters (P. 31 and P. 32) are used to set the low speed behavior of the drive. This parameter typically remains at 0 Hz 0–400 Hz, 9999 0 Hz
P. 32 Frequency Jump 1B: Maximum frequency to skip over to avoid very low fan airflow and unnecessary motor overheating. (9999: frequency jump not enabled)1
Note: Ensure that this is set equal to P.902 (screen a) and P.904 (screen a).
0–400 Hz, 9999 12.5 Hz
P. 33 Frequency Jump 2A: To avoid resonance noise caused by natural frequency of mechanical system, enter frequency just below noisy frequency 2. 0 to 400 Hz, 9999 9999
P. 34 Frequency Jump 2B: To avoid resonance noise caused by natural frequency of mechanical system, enter frequency just above noisy frequency 2. 0 to 400 Hz, 9999 9999
P. 35 Frequency Jump 3A: To avoid resonance noise caused by natural frequency of mechanical system, enter frequency just below noisy frequency 3. 0 to 400 Hz, 9999 9999
P. 36 Frequency Jump 3B: To avoid resonance noise caused by natural frequency of mechanical system, enter frequency just above noisy frequency 3. 0 to 400 Hz, 9999 9999
P. 37 Speed Display: Set the drive to display motor in RPMs (instead of Hz) by entering the maximum rated motor speed from the motor nameplate. When set to 0, the drive displays speed in Hz. 0, 0.01–9998 0
P. 68 Retry Wait Time: Defines the time delay (in seconds) before the drive attempts to restart the motor after a fault shutdown. 0.1–600 seconds 10 seconds
P. 72 PWM Frequency Selection: Allows you to reduce audible noise by changing the PWM frequency (Hz). 0–153 1
P. 73 Analog Input 1 Type: Defines the input signal voltage range and motor rotation direction.
  • 0: 0–5 VDC
  • 1: 0–10 VDC
0, 1 0
P. 77 Parameter Write Select: Enables or disables writing (changing) certain parameters and defines when parameters may be written.
  • 0: write when VFD stopped
  • 1: write disabled
  • 2: write enabled anytime
0, 1, 2 2
P.183 Enable Analog Input 2 (AI2) when terminal MRS is connected to terminal SD 0–8, 16, 18 4
P.902 (screen a) Analog Input 1: Minimum speed defined as frequency. 0–60 Hz 12.5 Hz

P.904 (screen a) Analog Input 2: Minimum speed defined as frequency. 0–60 Hz 12.5 Hz
P.904 (screen b) Analog Input 2: % of input current to start minimum speed ramp. 0–100% 38% (7.6 mA)
P.905 (screen a) Analog Input 2: Maximum speed defined as frequency. 1–400 Hz 60 Hz
P.905 (screen b) Analog Input 2: % of input current for setpoint (where motor reaches maximum frequency or speed). 1–100% 54.8% (11 mA)
1 If P. 32 = 9999, then the speed of the motor controlled by the VFD68 will not drop below P. 2 (minimum motor speed), regardless of the mode selected.
2 If the VFD68 supply voltage is greater than the motor rating voltage (such as when using a 208 VAC motor with a 230 VAC supply), enter the motor rating voltage for P. 19. This allows the motor to run cooler.
3 A setting value of 0 indicates 0.7 kHz. A setting value of 1 indicates 1 kHz. A setting value of 15 indicates 15 kHz.
