MMC Smart Drive Hardware Manual - INSTALLING THE MMC SMART DRIVE
exchanged within the system. The MMC Smart Drive is designed for use in industrial
environments, but some guidelines should be followed.
This section contains common system wiring configurations, size, and practices that
can be used in a majority of applications. National Electrical Code, local electrical
codes, special operating temperatures, duty cycles, or system configurations take
precedence over the values and methods provided.
Wherever possible, install wiring and related components in the following order:
1. main power line disconnecting means
2. transformer (optional)
3. fuses (SCPD)
4. motor control
5. line reactor (as required)
6. line filter (optional)
7. device protection fuses (as required)
8. drive
9. shunt resistors (optional)
3.12.1 Recommended Signal Separation
Kollmorgen recommends separation of low level signals (encoder, analog,
communications, fast DC inputs) from high voltage or high current lines. Maintain at
least two inches of separation.
Inside a control cabinet, connect the shields of shielded cables at the MMC Smart
Drive. It is recommended that factory cables (from Kollmorgen) are used between
MMC drives, controls, and motors to ensure CE compliance.
WARNING
Use care when wiring I/O devices to the MMC Smart Drive
and when plugging in cables. Wiring the wrong device to the
connector or plugging a connector into the wrong location
could cause intermittent or incorrect machine operation or
damage to equipment.
