3.6. Examples of Standard Connections
The following diagrams show examples of standard servo amplifier connections
by specifications and type of control.
Note for single-phase power supply specifications:
FSP Amplifier FSP-08A and FSP-15A are single-phase drivers. Main circuit
connection terminals (L1, L2, L3) remained.
These devices have terminal B3 and internal regenerative resistor. Observe the
following points.
1. Connect main power supply shown below to L1 and L3 terminals. Power
supply is single-phase, 220 to 230 VAC +10% to –15%, 50/60 Hz. If power
supply of 187 V (-15% of 220 V) or less is used, alarm A.41 indicating
voltage shortage, may occur when accelerating to max speed with max torque
of motor.
2. Short-circuit B2 and B3 terminals using the internal regenerative resistor. If
capacity of the regenerative resistor is insufficient, remove the lead between
B2 and B3 terminals and connect an external regenerative resistor unit to B1
and B2 terminals.
Cable type: P/ N YS -12
Host controller
FSP Amplifier is compatible with most PLC
motion controllers and indexers.
Brake power supply
Used f or a servomotor
with a brake.
