Invertek Optidrive P2 series Installation & Operating Instructions Manual page 39

Par Parameter Name
P2-23 Zero Speed Holding Time
Determines the time for which the drive output frequency is held at zero when stopping, before the drive output is disabled
P2-24 Effective Switching Frequency
Effective power stage switching frequency. The range of settings available and factory default parameter setting depend on the
drive power and voltage rating. Higher frequencies reduce the audible 'ringing' noise from the motor, and improve the output
current waveform, at the expense of increased drive losses. Refer to section 0 for further information regarding operation at higher
switching frequency.
P2-25 2nd Deceleration Ramp Time
This parameter allows an alternative deceleration ramp down time to be programmed into the Optidrive, which can be selected by
digital inputs (dependent on the setting of P1-13) or selected automatically in the case of a mains power loss if P2-38 = 2.
When set to 0.0, the drive will coast to stop.
P2-26 Spin Start Enable
0 : Disabled
1 : Enabled. When enabled, on start up the drive will attempt to determine if the motor is already rotating, and will begin to control
the motor from its current speed. A short delay may be observed when starting motors which are not turning.
2 : Enabled for Coast, Trip or after Mains Loss. Spin start is active only following the listed conditions, otherwise spin start is
disabled.
P2-27 Standby Mode Timer
This parameter defines time period, whereby if the drive operates at minimum speed for at least the set time period, the Optidrive
output will be disabled, and the display will show . The function is disabled if P2-27 = 0.0.
P2-28 Slave Speed Scaling Control
Active in Keypad mode (P1-12 = 1 or 2) and Slave mode (P1-12=5) only. The keypad reference can be multiplied by a preset scaling
factor or adjusted using an analog trim or offset.
0 : Disabled. No scaling or offset is applied.
1 : Actual Speed = Digital Speed x P2-29
2 : Actual Speed = (Digital Speed x P2-29) + Analog Input 1 Reference
3 : Actual Speed = (Digital Speed x P2-29) x Analog Input 1 Reference
P2-29 Slave Speed Scaling Factor
Used in conjunction with P2-28.

P2-31 Analog Input 1 Scaling
Scales the analog input by this factor, e.g. if P2-30 is set for 0 – 10V, and the scaling factor is set to 200.0%, a 5 volt input will result
in the drive running at maximum speed (P1-01)

Sets an offset, as a percentage of the full scale range of the input, which is applied to the analog input signal

P2-34 Analog Input 2 Scaling
Scales the analog input by this factor, e.g. if P2-30 is set for 0 – 10V, and the scaling factor is set to 200.0%, a 5 volt input will result
in the drive running at maximum speed (P1-01)
P2-35 Analog Input 2 Offset
Sets an offset, as a percentage of the full scale range of the input, which is applied to the analog input signal
P2-36 Start Mode Select / Automatic Restart
Defines the behaviour of the drive relating to the enable digital input and also configures the Automatic Restart function.
