For the main line power L1/L2/L3 and motor output current:
The P Series drive can be run on three phase or single phase 230 VAC input power. In most cases, the drive has the same current rating running on single phase as it does running on three phase. However, in the case of the PD-35P and PD-35C, the peak current is de-rated by 50% when running on single phase. The table below shows all power types and ratings for which P Series drives are suitable.
Output (Shaft)Power Ratings
|240/230/208 VAC 3 PH||240/230/208 VAC 1 PH||120 VAC 1 PH *||24-80 VDC*|
Note - current ratings are listed in A rms units
* The PD-04x power level can be configured to run from 120VAC input power or DC input power. See the section below that covers how to change the configuration for your input voltage.
* The PD-10x and PD-35x power levels MUST be used with 240/230/208 VAC. Running either of these drives on a lower voltage can damage them.
AC Input Power Connections (for DC see below):
The protective earth ground connection is made to one of the screw terminals on the bottom of the drive, on the heat sink directly. DO NOT USE THE 'N' TERMINAL FOR AC OR EARTH GROUND CONNECTIONS (this is not 'neutral').
For the control power C1/C2:
The P Series Drive's control board dissipates roughly 25 W while powered on. The control power terminals on the P Series Drive, C1 and C2, draw approximately 208 mA at 120 VAC and approximately 104 mA at 240 VAC. The difference in control power current draw between different P Series drives is negligible. The C1/C2 inputs cannot be powered by DC voltage.
Inrush current will be present on the terminals at power-up. Because of this, a 3 A time delay fuse is recommended for C1 and C2.
To operate the P series drives at low DC voltages there are additional software and wiring steps that must be conducted to ensure proper operating conditions.
Note - the Control Power (C1/C2) still require either 120VAC or 230VAC input power, these cannot be powered from DC input voltage.
NOTE: PD-10 and PD-35 require 208 - 240vac. Do not run PD-10 and PD-35 with 120vac or DC input voltage.
(For some lower bus voltage rating motors, some additional current loop gain setting changes may be needed. See below for those recommendations.)
In the Drive Support Tool software do the following:
- Hold the Alt key and then click the Engineering Setup (blue down arrow icon in toolbar).
- This will open a window allowing for the lower voltage configuration.
- For 120VAC operation, select the "Allow 110V AC Input" checkbox.
- For DC input operation, select the "Allow low voltage DC input" checkbox.
- Then click the Flash Save button (EEPROM icon).
- Remove factory installed jumper from PO/PI
- Apply 24-80VDC to PI and N [this is the voltage you want your motor to run at]
- Control power C1/C2 requires 110-230VAC single phase
- Your motor phases U,V,W connect to the standard connector as you would normally
You will find the default current loop gain settings to be more aggressive than desired. The symptom will be a high frequency audible noise from the motor when enabled due to this default current loop gain. This gain can be lowered using the P Series Drive Support software in the "Trace / Trigger Monitor" screen via the Gain Window button. See screen shot below. For 48Vdc bus voltages, a value around 50% will be appropriate and for 24Vdc bus voltages a value of around 25% will be appropriate.
