1 Introduction
1.1 Safety Information
DANGER!
Hazard of electrical shock! Circuit potentials are up to 480 VAC above earth ground. Avoid direct contact with the printed
circuit board or with circuit elements to prevent the risk of serious injury or fatality. Disconnect incoming power and wait 60
seconds before servicing drive. Capacitors retain charge after power is removed.
STOP!
DO NOT connect incoming power to the output motor terminals (U, V, W)! Severe damage to the PositionServo will result.
Check phase wiring (U, V, W) and thermal input (T1, T2) before powering up drive. If miswired, severe damage to the
PositionServo will result.
STOP!
Use only 10 V (peak to peak) or less resolvers (P4). Use of higher voltage resolvers may result in feedback failure and
damage to the drive.
WARNING!
Hazard of unintended operation! When the enable input remains asserted, the “Keep Alive” circuit (P5) will restart the
motor upon restoration of mains power. If this action is not desired, then remove the enable input prior to re-application
of input power.

1) Installations with high fault current due to large supply mains may require a type D circuit breaker.
2) UL Class CC or T fast-acting current-limiting type fuses, 200,000 AIC, preferred. Bussman KTK-R, JJN, JJS or equivalent.
3) Thermal-magnetic type breakers preferred.
WARNING!
The PositionServo drive runs on phase-to-phase voltage. For the standard drive, either a delta or wye transformer may be used for
3-phase input. However, for reinforced insulation of user accessible I/O circuits, each phase voltage to ground must be less than or
equal to 300VAC rms. This means that the power system must use center grounded wye secondary configuration for 400/480VAC
mains.
STOP!
For the E94 _020S1N_~ and E94_040S1N_~ doubler models, do NOT apply 240VAC to the N and L1 terminals. Severe damage to
the drive will result.

NOTE: Terminals T1 and T2 are used for motors with a thermistor only.
The PositionServo does not provide motor over-temperature protection. The user may connect a KTY motor thermal sensor to
the drive as detailed in section 4.1.1 and 4.5.2 of manual S94H201 if necessary to satisfy NEC requirements.
NOTE
Encoder cables manuafactured by Lenze AC Tech use 18 AWG wire for the T1 and T2 connectors. Customer-manufactured
cables may use a different AWG wire for the T1 and T2 connectors.

Technical Data
STOP!
This is only partial information on the ISO 13849-1 Safety Circuit. BEFORE using P8, read the COMPLETE DETAILED INSTRUCTIONS
for the ISO 13849-1 Safety Circuit in Section 4.1.8 of manual S94H201 (PositionServo Users Manual on the accompanying
CD and www.lenzeamericas.com).
Due to ISO 13849-1 regulations, a separate +24VDC external dedicated safety power supply must be provided to
the drive Safety circuits. The bypass +24V supply is intended for bypass purposes only and must not be used as the
control voltage to these circuits.

6 Safety Input2 ISO 13849-1 Safety Input 2 (+24VDC to Enable)
Evaluation and Testing of the ISO 13849-1 Safety Circuit
As part of the regulations for ISO 13849-1 safety circuit provision must be made for the user to periodically test the
safety circuits and that testing should be capable of identifying a single fault. The PositionServo drive uses the safety
status output (Pin 3) in conjunction with the display of the drive to allow the testing of the safety circuits.
The safety status output becomes active to indicate partial or full enable of the safety input circuits 1 and 2. If safety
input 1 or safety input 2 or both inputs are on then the safety status output will become active. The safety status
output must be connected to some visible indication for the operator to reference during test of the circuit.
As well as being used to test the correct operation of the safety circuits the safety status output can be used as an
indicator that the drive has been placed in the fully shut down condition (all safety circuits off). For example, if both
Safety Inputs have been Deactivated, the Safety Status is also Deactivated. If one of the Safety Inputs signals failed
to call for a shutdown, or if one of the Safety Circuits failed to shut down, the Safety Status signal remains Asserted
to alert the operator to the problem.
The procedure for testing the ISO 13849-1 safety circuit and the identification of a single fault on the system is given
below. The safety status output should be connected to a visible indicator (such as a lamp or LED) so the operator
can interpret its condition.
NOTE
Customer must size load so as not to pull more than 100mA.
