Connector Interface (summary)
CN1: Control signal input/output connector (DB26 Male) — pins for digital inputs/outputs and commons (examples: COM+, SON (Servo ON), ALM-RST (Alarm reset), POT (Positioning complete), INP (Position command pulse), SIGN (Pulse input direction), BRK (Brake output), COM- (common for DO)); many pins reserved for functions and some pins reserved/unused.
CN2: Encoder signal connector (DB15 Female) — encoder power and signal pins (5V, 0V, A+/A-/B+/B-/Z+/Z-, U/V/W encoder phase inputs, FG frame ground).
CN3 / CN4: Communication connectors (RJ45, for RS485 crystal head).
L1, L2: Main power input terminals.
P, D, C, N: Dynamic braking resistor connection terminals.
U, V, W: Servo motor output terminals — connect to motor U, V, W phases.
PE: Protective earth terminal — connect to supply ground and motor ground.
CHARGE LED: Bus capacitor charge indicator (LED ON = capacitor charged; do not touch power terminals while LED is on).
