Kollmorgen CE1025112
Product Brief: CE10251 belongs to the SERVOSTAR CD2 family — compact single-axis digital servo amplifier for brushless AC servo motors. “CE” = 230 VAC input version (vs CR = 400 VAC); 10 = 10 A continuous rating; 251 = firmware/config variant. CE1025112 appears to be a sub-suffix/variant label. These drives preceded the S700/AKD generations but remain in many legacy systems.
Detailed content
Typical Specifications (CE10xx — 230 VAC input, 10 A example):
-
Supply Voltage: 1Ø or 3Ø 200–240 VAC (CE = 230 V class)
-
Continuous Output Current: 10 A RMS (CE10250 = 3 A, CE10550 = 5 A — CE10xx number encodes current; 10251 = 10 A variant)
-
Peak Output Current: 2× continuous for short duration
-
DC Bus: internally regulated, ~320 VDC nominal from 230 VAC
-
Feedback: Resolver, incremental encoder, sin/cos encoder, Hiperface (some via option)
-
Control Modes: Torque, Velocity, Position (indexer optional on CD2)
-
I/O: Digital inputs/outputs, analog ±10 V setpoint
-
Communication: RS232 service port; optional fieldbus (Profibus, DeviceNet) on CD2+
-
Protection: Overcurrent, overvoltage, undervoltage, overtemperature, motor thermal input
-
Mounting: Panel mount in control cabinet, IP20
-
Operating Temp.: 0 to +45 °C (typical)
Features: Auto-tuning, digital filters, electronic gear, programmable acceleration/deceleration profiles. Compatible with Goldline B/M/EB and early AKM motors.
Notes: Legacy product — replacement recommended with S700 or AKD for new designs. Verify exact current rating from nameplate (10251 often = 10 A continuous @ 230 VAC). Parameter backup advisable before replacement.
