1. ZVD Description
This manual contains easy to follow information and procedures required to complete
the initial installation, wiring, and startup operation for the ZVD AC Vector Drive. Be
sure to observe all WARNINGS, CAUTIONS, and NOTES prior to proceeding with a
particular task.
Note: The standard ZVD Vector Drive is prepackaged in a NEMA 12 control cabinet.
The controller is mounted and all internal cabinet wiring is complete. The unit is pro-
grammed according to customer specifications. All that is required of the customer
is to make field wiring connections. The customer should become familiar with this
manual, particularly with regard to input/output selections and wiring techniques to
avoid electromagnetic interference (EMI) noise pickup, damage to equipment, and
personal injury.
1.2.1 The standard ZVD AC Vector Motor Drive and Speed Control consists of an AC
vector drive, mounted in a NEMA 12 control cabinet. The drive is mounted on
the sub-panel and pre-wired to a terminal strip for customer terminations. The
keypad from the drive has been relocated to the cabinet door via a connector
cable. A Pulse Generator card has been installed in the drive to provide closed
loop feedback.
1.2.2 The standard ZVD Vector Drive is available in four 230 VAC, 3 phase models (1,
2, 3, and 5 HP) and in four 460 VAC, 3 phase models (1, 2, 3, and 5 HP). The
control cabinet size varies, depending on the horsepower rating of the drive.
See the chart on page E-1 for cabinet sizes.
1.2.3 A standalone NEMA 1 version of the ZVD Vector Drive(s) is also available with
the Pulse Generator card installed. The standalone ZVD is not supplied with a
cable for use in remotely locating the keypad. The cable must be ordered sepa-
rately. Consult the factory for details.
1.2.4 For 380 VAC input voltage, use the corresponding 460 VAC drive version. If full
load at 380 VAC is required, use the next higher power drive and motor (e.g., if
operating conditions require 1 HP and the input voltage is 380 VAC, specify a 2
HP drive and motor).
1.2.5 In Vector mode, the ZVD Vector Drive provides a closed loop accuracy of 0.1%
of base speed under constant load. Closed loop feedback must be provided by
a 120 PPR (minimum) Hall Effect feedback sensor or encoder.
1.2.6 A vector (inverter) duty AC motor is required. Constant torque turndown of the
motor is 100:1.
1.2.7 The ZVD Vector Drive meets UL, CUL (CSA), and the CE low voltage directive.
With the optional EMI filter, the drive also meets the CE EMI requirements.
1.2.8 In the event the motor drive assembly has to be located in a hazardous loca-
tion, an optional intrinsically safe barrier is available to install in the ZVD Vector
Drive cabinet to limit sensor current to safe levels.
1.2.9 Appendix A contains a list of ZVD Vector Drive options and auxiliary equipment
by part number.
