Pump Drive - SK 072.1F-71S/4 CUS with Motor-Mounted SK 200E

Overview
The pump drive assembly consists of a NORDBLOC.1
inline gearbox with a 1/3 hp motor (SK 072.1F-71S/4)
and motor-mounted SK 200E AC vector drive.
A 1/3 hp (0.25 kW) rated AC vector drive rated for
1-phase 230VAC input is mounted directly to the 1/3
hp (0.25 kW) rated motor which is wired for low volt-
age (3-phase 230VAC). The SK 200E AC vector drive
includes an internal 24VDC control power supply
without the need for an additional module. The drive
assembly includes 2x analog inputs, 4x digital inputs,
and 2x digital outputs. An 8-pin M12 quick-discon-
nect receptacle is provided as the means of connect-
ing the control signals from the control panel.
A 4-20mA signal is connected to an analog input and
is used as the speed reference (0-100 Hz). Two of the
digital inputs are used to control the Drive Enable
and Rotation Reversal functions. Finally, a 24V digi-
tal output is used to provide feedback to the control
panel that the drive is running.
Initial Checks – Pump Drive
Before applying mains input power to the drive, per-
form the following checks:
1) Check the Type and Part Number on the name-
plate of the AC vector drive. If either is not as listed
below, the AC vector drive does not have the correct
rating and may need to be exchanged.
a. Type should be SK 200E-250-123-A
b. Part Number should be 275226103
2) Access electrical connections by following
procedure shown below.
a. Confirm input AC supply voltage is turned off.
b. Loosen the 4 hex sockethead screws (4mm).
c. Carefully lift the AC vector drive off the
connection unit
d. The electrical connections and the option slots
are now freely accessible.
