|
|
|
|
P007 | Keypad control | 0 - 1 | 0 = The RUN, REVERSE and JOG buttons are disabled. Control is | |||
|
| [0] | via digital inputs (see parameters P051 - P053). ∆ | and ∇ may | ||
|
|
| still be used to control frequency provided that P124 = 1 and a | |||
|
|
| digital input has not been selected to perform this function. | |||
|
|
| 1 = OPm2 buttons are enabled (can be individually disabled | |||
|
|
| depending on the setting of parameters P121 - P124). The | |||
|
|
| digital inputs for RUN, JOG and ∆ / ∇ are disabled. | |||
|
|
|
|
|
| |
P009 • | Parameter protection setting | 0 - 3 | Determines which parameters can be adjusted: |
|
| |
|
| [0] | 0 = Only parameters from P001 to P009 can be read/set. | |||
|
|
| 1 = Parameters from P001 to P009 can be set and all other | |||
|
|
|
| parameters can only be read. |
|
|
|
|
| 2 = All parameters can be read/set but P009 automatically | |||
|
|
|
| resets to 0 when power is removed. |
|
|
|
|
| 3 = All parameters can be read/set. |
|
| |
|
|
|
|
|
| |
P011 | Frequency setpoint memory | 0 - 1 | 0 = Disabled |
|
| |
|
| [0] | 1 = Enabled. The setpoint alterations made with the ∆ | / ∇ buttons or | ||
|
|
| digital inputs are stored even when power has been removed | |||
|
|
| from the inverter. |
|
| |
P012 • | Minimum motor frequency (Hz) | 0 - 120.00 | Sets the minimum motor frequency (must be less than the value of | |||
|
| [0.00] | P013). |
|
|
|
P013 • | Maximum motor frequency (Hz) | 0 - 120.00 | Sets the maximum motor frequency. |
|
| |
|
| [50.00] |
|
|
|
|
P014 • | Skip frequency 1 (Hz) | 0 - 120.00 | A skip frequency can be set with this parameter to avoid the effects of | |||
|
| [0.00] | mechanical resonance. Frequencies within | |||
|
|
| setting are suppressed. Stationary operation is not possible within the | |||
|
|
| suppressed frequency range - the range is just passed through. |
| ||
P015 • | Automatic restart after mains | 0 - 1 | Setting this parameter to ‘1’ enables the inverter to restart | |||
| failure. | [0] | automatically after a mains break or ‘brownout’, provided the run/stop | |||
|
|
| switch is still closed or the link is fitted, P007 = 0 and P910 = 0, 2 or 4. | |||
|
|
| 0 = | Disabled |
|
|
|
|
| 1 = | Automatic restart |
|
|
P016 • | Start on the fly | 0 - 2 | Allows the inverter to start onto a spinning motor. |
|
| |
|
| [0] | Under normal circumstances the inverter runs the motor up from 0 Hz. | |||
|
|
| However, if the motor is still spinning or is being driven by the load, it will | |||
|
|
| undergo braking before running back up to the setpoint - this can cause an | |||
|
|
| overvoltage trip. By using a flying restart, the inverter ramps up the output | |||
|
|
| voltage at the setpoint for the period defined by P020. |
|
| |
|
|
| 0 = | Normal restart |
|
|
|
|
| 1 = Flying restart after power up, fault or OFF2 ( if P018 = 1). | |||
|
|
| 2 = | Flying restart every time (useful in circumstances where the | ||
|
|
|
| motor can be driven by the load). |
|
|
P017 • | Smoothing type | 1 - 2 | 1 = Continuous smoothing (as defined by P004). |
|
| |
|
| [1] | 2 = Discontinuous smoothing. This provides a fast unsmoothed | |||
response to STOP commands and requests to reduce frequency. Note: P004 must be set to a value > 0.0 for this parameter to have
any effect.
