IMPULSE®•G+ & VG+ Series 4 Instruction Manual - February 2017
3-4
• To reverse the direction of rotation, program B03-04 = 1 (exchange phases), or interchange any
two motor leads (changing R/L1, S/L2, or T/L3 will not affect the shaft rotation direction) as well
as encoder phasing (F01-02 = 0/1 or swapping A and A
wires).
• Use shielded cable for all low-level DC speed reference signals (0 to 10 VDC, 4 to 20 mA).
Ground the shield only at the drive side.
• Please observe National Electrical Code (NEC) guidelines when wiring electrical devices.
• IMPORTANT: All wire connections must have strain relief, and must not apply downward
pressure to the terminals on the drive.
NOTE: Failure to observe these warnings may result in equipment damage.
CAUTION
Do NOT connect external dynamic breaking units to drive braking resistor terminal “B2”.
Connect positive external dynamic braking unit terminal(s) to drive terminal “+3” and negative
external dynamic braking unit terminal(s) to drive terminal “-”. When drive terminal “+3” is
unavailable, use terminal “B1”.
